Is it okay for my partner to ejaculate inside of me during unprotected anal sex?

Dear Reader,

Sex and love can be messy, and whether or not you're in a committed relationship, one advantage of using condoms is that it keeps things clean in the aftermath (literally!). Condom use should always be encouraged until all partners have been tested for STIs and given a clean bill of health. Once you're past that, the good news is that semen is safe and simple; containing mostly water, fructose (a type of sugar), secretions from the prostate, testicles, and glands, and of course, sperm. Although some people can be allergic to their partner's semen, most don't have any bad of reaction to it, and ejaculated semen is harmlessly absorbed into the receiver's body. 

Signs of semen allergy include redness, burning, itching, and swelling on the body part that touched the semen. Those who have more severe reactions might have hives, itching all over the body, and difficulty in breathing. If you experience any of those symptoms, you might want to see your health care provider right away to make sure it doesn't get worse. If you are still worried about the risks of ejaculation into your anus, you might want to discuss it with your fiancé to figure out alternatives to this, such as using a condom only for anal sex, or having him pull out before he ejaculates. Keep in mind that semen may still come out of his penis while he is inside you, though there won't be as much of it.

As long as you're both free of infections, there is really no harm in having your fiancée ejaculate during unprotected anal sex. There is also nothing wrong with going to the bathroom to get the semen out after the deed is done, although it is not necessary. Best of luck keeping it clean!
