Do use protection
You may think that wearing a condom for anal sex isn’t necessary since she can’t get pregnant, but the spread of sexually transmitted infections (STIs) is actually more likely with anal penetration than with vaginal. The skin around the anal area is thinner and more susceptible to tiny cuts and tears which allows STIs through. So unless you’re 100% sure both of you are monogamous and disease-free, putting a condom on for anal sex is essential.
Do let her set the pace
Make sure you and your partner both enjoy the anal sex experience by letting her call the shots. How fast, how far and how hard should all be up to her. You can’t be as rough or enthusiastic as you might be with vaginal intercourse — at least not right away. Let her get used to it by going slow, and if she says stop, stop immediately, or she may decide anal is no longer an option.
Don’t penetrate elsewhere afterward
Don’t put your penis in her butt and then immediately penetrate another part of her body (i.e., vagina, mouth). You may have picked up bacteria at the back door that could cause infections elsewhere. Plus, it’s gross. Yes, porn girls love them some ATM, but unless your girl specifically asks for it, don’t go there.
There are rules for a reason
It may seem like there are a whole lot of rules for something that should be fun, but they really are for your (and her) own good. Giving your girl a bad anal sex experience virtually obliterates your chances of ever doing it again. Make it good for both of you by following these important dos and don’ts.
