I think most people, certainly in britain ,do it in clubs and stuff. Have only done it a few times at home is very nice either way really. I just prefer being around people and meeting new people when I am on it. Quite a few times when I have been out clubbing I have ended up at strangers houses after the club finishes just chilling out. I would never do this usually but on Ecstacy it just feels natural. Basically all your social barriers come down and everyone is really open and friendly.
