Well you shouldn't have any problems talking a guy into it. What's that old saying?......"if a guy wants sex he has to work for it.....If a girl wants sex, all she has to do is show up!"...Lol
the best way to have a super intense orgasm during anal sex is either for you to be on top so you are the one cotrolling penetration depth and speed or you on your back with a pillow underneath your butt. In both cases make sure to stimulate yourself with your hand or better, with a vibrator. Doing it "doggy style" is only for those who are used to anal because in this position it is harder to relax and the anal canal is much tighter. Have fun!
me and my wife have had anal sex since a month after we met about 6 years ago. I finally got her to take it nice and slow only got in halfway about 4 inches for 2 months or so than she let me know when she wanted it deeper. Everytime since the first time she has orgasm to getting up in her ass. That's all she wants now and I love it. Vaginal is occasionl:)
