RISKS: You can't get pregnant from unprotected anal sex unless semen gets into the vagina, but it's still a Really Bad Idea. Here's why:
Unprotected anal sex (with a penis) is a high risk for sexually transmitted diseases like HIV, herpes, warts (HPV), hepatitis B, gonorrhea and syphilis. Why is unprotected anal sex such a high risk? Because the tissue inside your anus is very delicate and tender, and tiny tears or scrapes can happen without you even noticing. Then if your partner cums inside you or has genital warts or herpes, it is very easily transmitted.
