I have red sticky discharge that was pink. yesterday i had anal sex for the first time with my boyfriend and he ejaculated in me. help.

Discharge where?: If the discharge is rectal, it's a combination of semen and blood. The rectum isn't as well designed as the vagina for penile penetration and the inner lining can get inflamed or abraded. For this reason, I discourage anal intercourse in heterosexual couples. Have a heart to heart talk with your BF about less injurious ways to enhance your sexual relations. Best wishes to you both.
