For me, I actually expected orgasm to be different. I wasnt sure if I expected it to be stronger, or weaker etc, but I expected some change.
I must say, I havent really noticed any change actually.
And this experience includes comparisons of masturbation and ->-bleeped-<-s pre and post hysto.
As for the other type of sexual activity youre asking about, (either "door"), Im no help there.
