I'm doing some personal research on the potential for different drugs to improve sexual function, and in particular intensity to orgasm. I've read what's available on the forum already, but there's not enough info so thought as I research things I'd share findings, thinkings, and results of my personal experimentation.

Note about me for context:
I'm male 50+ and suffer from anorgasmia (inability to climax), I can ejaculate but it's very unrewarding. I've had issues with excessive alcohol use for most of my pubescent life - given alcohol can be an issue in itself, my 1st goal is to give it up. I generally don't take Serotonin reuptake inhibitors (which are known to cause issues with ejaculation/erection) with the 1 exception being MDMA, which prevents erection during the peak of MDMA roll, but has on 1 occasion allowed me to climax during the after glow phase of MDMA.

I'm a recent convert to poly drug use, but have for the past 30 years avoided psychedelics after taking a heroic dose of LSD in my youth, however microdosing is an option, and I have recently ordered Hillbilly mushrooms and 2CB to experiment with at lower doses (but likely higher than a microdose). MDMA, Cannabis, GBL, benzos, cocaine, soma, pregabalin, and mephedrone are all in my box - yes I'm aware of negative effects some of these have on ability to ejaculate/get an erection. Despite the long list of drugs I generally dose low and/or like combos at lower doses.


Strongest → weakest contribution to the orgasm reflex
RankNeurochemical Factor
1️⃣ Noradrenaline (Norepinephrine)Drives the sympathetic “release reflex” — the actual physical trigger for orgasm. Without NE activation, climax cannot occur.
2️⃣ Dopamine spikeProvides the reward, motivation, and pleasure surge that pushes the system toward orgasm. High dopamine makes climax possible and pleasurable.
3️⃣ Reduced serotonin toneSerotonin acts as a brake on orgasm. Lower serotonin removes inhibition and allows the reflex to fire. High serotonin blocks orgasm.
4️⃣ OxytocinEnhances pleasure, bonding, and intensity of orgasm but does not trigger it. Oxytocin shapes the emotional quality, not the mechanical reflex.

How each neurotransmitter contributes, and what pharmacology increases or decreases it

Neurochemical Requirement for ClimaxPharmacology That Increases ItPharmacology That Decreases ItClinical Meaning for Sexual Function
Dopamine spikeDopamine releasers: methamphetamine, amphetamine, MDMA, MDA, cathinones
Dopamine reuptake inhibitors: cocaine, MDPV, methylphenidate
Indirect modulators: nicotine, cannabis, ketamine
Dopamine blockers: antipsychotics
Dopamine suppressors: opioids (long‑term), SSRIs/SNRIs (indirect)
Dopamine drives desire, motivation, pleasure, and the “reward” of orgasm. Too much → overstimulation → orgasm difficulty. Too little → low libido, anorgasmia.
Noradrenaline activationNoradrenaline releasers: methamphetamine, amphetamine, MDPV, cocaine
Moderate releasers: MDMA, MDA, ephedrine
Modulators: nicotine, caffeine
Noradrenaline suppressors: opioids, benzodiazepines, alcohol (later phase)Noradrenaline triggers the sympathetic release phase of orgasm. Too much → overstimulation, erectile issues. Too little → weak orgasm or inability to climax.
Oxytocin surgeIndirect releasers: MDMA, MDA, GHB/GBL
Moderate modulators: psilocybin, LSD, mescaline, 2C‑B, ketamine
Direct agonist: oxytocin nasal spray (clinical)
Oxytocin suppressors: opioids, cocaine, methamphetamine, MDPVOxytocin creates emotional intensity, bonding, and pleasure during orgasm. High oxytocin = more satisfying climax. Low oxytocin = mechanical or emotionally flat orgasm.
Reduced serotonin toneSerotonin antagonists: (rare in recreational use)
Low‑serotonin states: post‑MDMA, stimulant comedown, fasting, stress
Serotonin releasers: MDMA, MDA
Serotonin agonists: LSD, psilocybin, mescaline
SSRIs/SNRIs: strong inhibition
Serotonin inhibits orgasm. High serotonin = delayed or absent orgasm. Low serotonin = easier climax.

Drugs with notable positive contributions to one or more orgasm‑relevant systems​

Drug / ClassDopamine (GO)Noradrenaline (Release)Oxytocin (Bonding)Serotonin (Brake)Net comment for climax (mechanistic, not a recommendation)
Low‑dose amphetamine (therapeutic)✅ (moderate spike)✅ (moderate)❌ (minimal)✅/⚠️ (no big increase)Can increase desire and arousal; at higher doses often delays or blocks orgasm.
Low‑dose methylphenidate✅ (moderate)✅ (moderate)❌✅/⚠️Similar to amphetamine: can support arousal; high doses → overstimulation.
Nicotine✅ (mild)✅ (mild)⚠️ (very indirect)✅ (no major increase)Slightly pro‑arousal; effects are small and highly individual.
Caffeine⚠️ (very mild)✅ (mild)❌✅Can support alertness and arousal; too much → anxiety, performance issues.
Low‑dose alcohol⚠️ (mild dopamine early)⚠️ (mild NE early, then ↓)⚠️ (bonding via disinhibition)✅ (no serotonin surge)Can reduce anxiety and help climax in some; higher doses quickly become anti‑sexual.
Cannabis (light use)⚠️ (indirect dopamine)⚠️ (variable)⚠️ (can enhance bonding)✅ (no big serotonin increase)For some: increased pleasure and orgasm; for others: anxiety or detachment.
GHB/GBL (low dose)⚠️ (indirect dopamine)⚠️ (mild)✅ (strong oxytocin release)✅ (no serotonin surge)Can increase pleasure and bonding; big consent and overdose risks; higher doses are strongly anti‑sexual.
MDMA✅ (moderate dopamine)✅ (moderate NE)✅✅ (very strong oxytocin)❌❌ (very high serotonin)Desire and bonding ↑↑, but orgasm often blocked—especially in men—because serotonin is too high.
MDA✅ (moderate)✅ (moderate)✅ (strong)❌❌Similar to MDMA but more psychedelic; same orgasm‑blocking issue.

I'm especially interested in
  1. Which drugs improve ability to climax/intensity
  2. What the minimum dosage required is to improve sexual function
  3. If microdosing of these compounds is viable
While I enjoy getting high that's not my primary motivator, frequency & dependency is a factor here so ideally I'd want to reduce risk and harm as much as possible while still getting the "benefits".

There are other things that play a factor in orgasms, link to another post here with brief summary. There are also other things which can help e.g. kegals, exercise etc. I don't plan on covering either the factors directly or other techniques but they are things I am also actively looking at.

For this thread I would like to keep specifically to Pharmacology and how it effect orgasm.

Really keen to hear thoughts, suggestions, and experiences from others - I've got a lot to learn!

I honestly think you dont need any recreational drugs, I have two suspicions which are far more likely candidates to your weak orgasms:

1. You have potential pelvic floor issues, when you ejaculate does it shoot out or dribble out? Do you have a tight sensation around your pelvic area? Does it spasm? Is peeing easy or difficult? Does your bladder not feel completely empty after you pee?
You potentially have too weak or too tight of a pelvic floor. I would visit a pelvic floor therapist if you suspect you have these issues and see if you need exercises for your pelvic floor.

2. It might be a hormonal issue, have you had your testosterone levels checked? Not only that but a full hormonal panel, total testosterone, free testosterone, SHBG, LH, Estrogen and prolactin.
Even if your testosterone and SHBG are in range your Estrogen could be too high or too low causing issues with orgasm or sexual enjoyment. Prolactin could also be a culprit, if your prolactin is too high it will decrease the sensitivity and also affect your refractory period.


So I would get those two things checked out first. Pelvic Floor and full hormonal panel to see if theres something to be done there

thanks for additional ideas, ejaculation shoots out, no tight sensation, and it does spasms. I've never had real issues with peeing in my life, but maybe a slightly more difficult as I've got older if I try and it's not a full bladder. Bladder feels empty after I pee.

will have a chat with my doctor about hormonal issues, really good idea thanks
 
I believe that orgasms (in men) under the influence of drugs are not better, but different.

That in itself is enough.
