My wife has a hard time with anal sex. When I get in it hurts her and I can't get in all the way. Any suggestions? She still lets me though.
Anyone can and usually does have a difficult time with anal penetration the first few times (and subsequent times as well, if they are not penetrated regularly).
Anal and vagina sex are
very different creatures and must be approached
very differently. It can take someone a long time to be relaxed enough to have enjoyable anal sex, especially if it is not something that they do frequently.
As the top, even when the anus feels over-lubricated, it can still feel abrasive to the person being penetrated (and I've been in both places). Take LOTS of time, have LOTS of foreplay, go VERY slowly, use lubes and fingers to let her get used to you.
Oh, and make sure she cleans out first. You have to clean the turkey before you stuff it.
To NJQT's point, my bud txbearjoe once joked (When I told him I had a neighbor who wanted me to tell him how he could successfully fuck his wife up the ass) "Why would a straight man want to fuck a woman up the ass?"
Too funny.
