Personlally first off you need to be a erotic creature as all drugs will only boost who you are. Being chemical you could ofcourse simulate falling in love by casrefully playing with the different reseptors in your brain knowing your research chemicals. You do need increased dopamine and serotonine levels as a basic goal - norepinephrine low. From there chose the drugs that does just that - fiddling with serotonine and dopamine reseptors.
Personal favourites is cocaine's and their RC's alternatives as a-pvp, MDPV and such.
In the tryptamine department 5-meo-mipt is the closest you get to MDMA.
If you ever get your hands serotonine releasers, these are great to enhance any experience. But as always - talking sex gets you sex! Doing drugs while talking sex, usually gets more sex - funkier and crazier.
Stay away from downers, unless its the girl and you enjoy a sack of potatoes and she enjoys being the sack of potatoes.

Oh the thread was to long, just some responds.
I used to get incredibly horny on meth. Sadly, not any more. 
Nowadays it just gives me the urge to clean my house.
The one thing I NEVER in my life wanted to do on any stims is clean anything else than a dildo! No joke, pun intended! Why the hell would you want to waste good drugs on house cleaning, I never got it. Maby because i ran a cleaning company once, maby, could be.
So definately Viagra or other ED drugs dont make me horny.
Years ago when I used to do occassional MDMA I noticed that it made me more horny but it also lowered my standards with whom I would like to have sex as everyone appeared so sexy while on it but when I woke up I might had a horror show
I share your ejaculation problem, due to overly use of stims. Sure I could stop using - but hey - my addiction pain kicks back in - so totally agreed. I cannot use viagra though as the rise in heartrate is not what I need at times and it totally knocks the air out of me so Cialis is better for meg - though - viagra is definately the best sollution when devine intervention is needed to get the job done.
MDMA... Haha, what a great observation! One could add that the other side also enjoys confidence in a man. MDMA also brings that to the table, a direct forced attraction from a guy just screaming with hes body - I WANT YOU NOW! You can see that working on all levels :D
I've never taken viagra, I just wanted to try and save all the viagra and extendz or w/e posts. Would be interested in trying it though, but at $15 a pill!? Are you insane... could get... well no pricing.
They are worth it, so are cialis. Go original, try it. Not like drugs are free - you are investing in great sex with an erection compared to th alternative which I guess is the reason why I love them both Viagra and Cialis! The only way I can enjoy drugs and sex at the same time!
most stimulants really. but i dont think they "force" you to be horney. for me its mental really. there have been times where im on amphetamines and my thoughts drift to sexual ones and i get horney but i can also stop my mind from going there so i wont go crazy.
Interesting point. Normally I am the one with the sexual jokes all the time, a friend of mine never does them as he wants to talk about fighting. It is without doubt only enhancing or potentiating your own desired. You need to be horny from the getgo, from there you can reach the sky. On the other heand 10 valiums and a bottle of rum is probably not a good sexual sollution! :D
I puked the entire next day if I so much as moved my finger.
To be honest, I think the problem here lies with you and your husband maby not being totally clear on what you were doing and you being over run a little. My 2 cents. If you ever do it again talk it over before what and were limits are.
haha looking up the MDPV on google shows an image of the atoms of the compound. They instantly stood out to me as a penis with two balls. :-/
OMG I had to check myself, it's a god damn dick! No wonder - I want that stuff. I already loce cocain, a-pvp so naturally MDPV is just awesome as its the same brand.
5-MeO-DIPT This sexes you up.
What you think about 5-meo-mipt compared? Never tried 5-meo-dipt, did the 4- series though but landed on 5-meo-mipt.
