Follow Mrs. H's advice. Also, try small toys or other safe insertable objects many times before. Get to the point where you enjoy something that is only as thick as a finger, then more on to sometghing as thick as a thumb, you get the point.....heck enjoy fingers first..... It is ok if it takes you days to work up to that.......do it alone if your boyfriend or girlfriend is impatient. Do it alone anyway......any time you'd like.
Maybe when your drunk you're not thinking about it as much and you become more relaxed. As people have said here before, try starting with a finger. Get ur partner to put his finger in there when you're having sex. You'll either get a taste for it and learn how to relax it or you'll hate it. Only one way to find out. ps: you'll love it!! hehe
being drunk migh be a good time to do it. I know several girls who find it much harder to cum when they are drunk(ive found this is the best time to ask for it, hehe) one of my ex's always said her ass was exit only. Until one time when she was all fucked up on OC's and was having trouble climaxing. we had alread been fuckin for a while so she was really relaxed. I put my fingers in her ass and she liked it, after a few mintues i put in 2 and she said she was getting closer to cumming. than she asked me to fuck her up the ass. i got down and licked her ass ot mmake it super wet. than i got up and put the tip of my cock in. I had her tell me when she was ready for more to go in. It took us a good 15 mins until her ass was strethed enough to take me all the way. i started pumping slowly as she rubbed her clit and she came so hard she said it was the beast orgasm of her life. made her squirt for the first time. now she is an anal addict. i hooked up with her again a few months ago and we only did anal. she tole me she does anal sex every time she fucks now. the ket is making sure the girl is in charge. the only time i ever hurt a girl doing her up the ass was a girl who didn't talk during sex(i hate that) wel i was trying to go slw but it is hard for the guy to tell how slow to go. i was drunk off my ass too, u shold probably make sure the guy isn't too wasted
