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
Ordered strongest → weakest within each mechanism
I'm especially interested in

Strongest → weakest contribution to the orgasm reflex
| Rank | Neurochemical Factor | |
|---|---|---|
 Noradrenaline (Norepinephrine) | Drives the sympathetic “release reflex” — the actual physical trigger for orgasm. Without NE activation, climax cannot occur. | |
 Dopamine spike | Provides the reward, motivation, and pleasure surge that pushes the system toward orgasm. High dopamine makes climax possible and pleasurable. | |
 Reduced serotonin tone | Serotonin acts as a brake on orgasm. Lower serotonin removes inhibition and allows the reflex to fire. High serotonin blocks orgasm. | |
 Oxytocin | Enhances 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 Climax | Pharmacology That Increases It | Pharmacology That Decreases It | Clinical Meaning for Sexual Function |
|---|---|---|---|
| Dopamine spike | Dopamine 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 activation | Noradrenaline 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 surge | Indirect releasers: MDMA, MDA, GHB/GBL Moderate modulators: psilocybin, LSD, mescaline, 2C‑B, ketamine Direct agonist: oxytocin nasal spray (clinical) | Oxytocin suppressors: opioids, cocaine, methamphetamine, MDPV | Oxytocin creates emotional intensity, bonding, and pleasure during orgasm. High oxytocin = more satisfying climax. Low oxytocin = mechanical or emotionally flat orgasm. |
| Reduced serotonin tone | Serotonin 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 / Class | Dopamine (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
- Which drugs improve ability to climax/intensity
- What the minimum dosage required is to improve sexual function
- If microdosing of these compounds is viable
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!
