Don't knock it till you try it...4 or 5 times.

Anal sex in itself is NOT harmful. The only risks are infections and STD's, and common sense will help you past these. It will not cause incontinence, and it will not make your anus bigger. However, if you have any doubt about your partner's STD status, you should not be having ANY sexual contact, including anal sex, with or without a condom. Both participants should wash genital and anal areas before and after anal sex, and the penis (or finger, dildo, shampoo bottle, or whatever) should never be inserted into the vagina after anal penetration until it has been thoroughly washed.

But the first time it's going to hurt. A lot. Go slow and use plenty of lube. It will hurt the first few times. My wife did not enjoy anal until the third or fourth time we did it (honestly, I don't know why she wanted to keep trying it.) But she started to enjoy it and now she loves it. We don't do it often, but when we do it's great for both of us.

Everything in moderation.
