Long-term, HIV negative partners sometimes choose to use condoms for anal sex for hygienic reasons. Women are at greater risk for UTIs than men because their urethra is shorter, giving bacteria better access to the bladder. The penis should not come into contact with the vagina after anal sex unless a new condom is worn or the penis is cleaned with soap and water. Stop having anal sex if you notice bleeding, and see a doctor if bleeding continues. Take a break from it if you feel irritation or develop hemorrhoids.
Some people feel some shame or guilt after having anal sex.
I think that is a normal response. Society teaches us that anal sex, among other things, is taboo. Remember, people have done it for ages. You should do what gives you pleasure and allow yourself to explore your sexuality without imposing moral imperatives.
