Ecstasy Drug ?

I've never experimented w/ illegal-drugs thus don't have much knowledge beyond what I've heard mentioned on-and-off.

Back in the early-2000s I had a semi-fave that was once telling me about her and her BF renting a hotel-room and having great sex while on Ecstacy.

More recently (a few weeks ago), I was at a mixed-dive I go to from time-to-time - a curvy/busty (DDs) ebony I've known for a bit approaches me as she usually does whenever she sees me (known her maybe a year and have kicked-it w/ her ITC maybe 5 or 6 times) - my previous time w/ her (~ 2 months ago) she had asked me if I got tested routinely for STDs b/c she wanted to fuck me OTC raw - I said I did and she gave me her # but I never followed thru since OTC is not my M.O. and neither is me committing to any one dancer.

So my most-recent visit w/ her a couple of weeks ago she comes up to me while I'm sitting in the main-room - she approaches me as she usually does and she's pretty-affectionate and there's a good amount of mutual groping while we sit in the main-room - they announce a 2-for-1 and not wanting the 2-for-1 to go to waste I ask her if she's up for the 2-for-1 to which she says yes.

We go into the curtained dance-booth which offers privacy - while we're waiting for the 2-for-1 to start (they usually play a preliminary song while announcing the 2-for1 which can go for 2-minutes or so to give the dancers time to work the floor for the 2-for-1) - while waiting for the 2-for-1 to start ebony tells me "you don't do anything uncovered w/ the other girls do you?"; to which I answered "no" (it's an extras-place and she knows my M.O. of liking to get w/ several dancers during a visit) - so I answer "no" to I don't do anything uncovered w/ the other girls to which she says "good b/c I'm in the mood to suck your dick"; in the past everything w/ her had been covered) - the 2-for-1 starts - she gets full-nude and immediately drops to her knees and begins mouth-to-head resuscitation - she going at it like trying to take the chrome off a bumper alternating b/w BBBJ, and Russian w/ her full natural DDs, but mostly BBBJ - somewhere around the middle of song #2 I guess her mouth is a bit-tired and she gets on me FCG and makes out w/ me and at some point bare-little-Papi slips in her vag and she rides me like that for about half-a-song - she then hops off and goes back to BBBJing the shit out of little-papi along w/ more Russian - all in all it was 4-songs (2-for-1 + 2-regular-songs) - we stop at the end of the 4th-song and she says something along the lines of "I am so horny - I did some ecstasy and I'm lit" - I was a little light-headed from the experience and just-smiled (also b/c I don't have much if any knowledge/experience w.r.t. ecstasy and w.r.t. ecstasy and sex).

Have any of you had experience w/ ecstasy and ecstasy+sex, whether you using it or your partner? What were the effects, good/bad/indifferent? Not that I'm thinking of experimenting; just curious.
