So I am a 19 year old female named Jessica and I really enjoy anal sex, anal masturbation, and anal creampies. I especially like anal creampies. Just the thought of having semen inside my anus excites me. Is this a normal and healthy thought/feeling? Also, I have more questions.

When it comes to sexual thoughts and desires, "normal" isn't something we can easily determine, since the range of personal desires is so large and there isn't an easy way to determine how common something is. But we can certainly say that there's nothing wrong or unhealthy with feeling that way! It's absolutely fine to have this desire. What other questions do you have?

What happens to the semen when its inside the anus?

It just stays there until it comes back out; there isn't anything in particular that happens to it.
