My boyfriend talked me into having anal sex.  After doing it several times he wanted to have an orgasm in me.  I finally let him.  No we did not use any protection.

I am now having a loose bowel and some blood in it.  What exactly does this mean and is it serious.
I am worried and will never let him do it again.  I do let him use his finger in my anus while we are having sex and really enjoy it.  Is there anything wrong with that? Please let me know something quickly  I am feeling pretty stupid for letting him have the orgasm in me.

Unless your boyfriend has some sexually transmitted disease, you don’t have anything to worry about, and if he does, then you were at risk when having vaginal sex as well, unless you were using condoms to protect yourself against an unintended pregnancy.  It is true that anal sex carries a higher risk than vaginal sex because it is more likely to cause open sores and bleeding, which aids in the transmission of viruses. But no matter how you’re having sex, the bottom line is that your boyfriend (and you as well) should be tested for STDs and if he comes up clean, then you have nothing to worry about, and if he doesn’t, well then you do. But if he is disease free, you can go ahead and let him ejaculate inside of you without any additional worries. Your loose bowel movement could well have come from some other source, like something you ate, and the bleeding may have come because you had opened some wound or two in and around your anus, which then bled some more when you had a bowel movement, though I am not a medical doctor and this is only speculative.
