Extacy

I tried it once over in Amsterdam, but I was at a rave party. All I know is that I had undepletable energy and felt in the best mood of my life. Mentally though, I was really out of it, and I did have a pretty bad coming-down later on. Definitely in no position for scoring, haha.
 
Yes...the tactile sensations are unbelievable, but orgasm is virtually impossible.

That may be true for guys... quite the oposite for me.

Apparently it is really euphoric but I've also heard that sex after is never the same because you're always wanting to recreate what it was.

Hmmm, I wouldn't say so. I have had sex on E many times and sex without many many times since and I don't find myself hankering for the E-buzz. The physical high of E-sex is fantastic but it is different. I have a lot more concentration to give my partner when I'm straight, and vice versa of course. I've better orgasms and better sex in general without E, or any other stimulant for that matter.
