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

My fiance and I frequently enjoy anal sex. We no longer use condoms with each other during vaginal sex or anal sex. He enjoys ejaculating in me during anal sex and I don't mind it. Immediately afterwards I go to the bathroom and get out his cum, but sometimes it takes awhile for it to all come out. I'm wondering if this is OK to do or if it is harmful to my body because I do enjoy it and would like to continue. I just don't know anyone else who does this and wonder if it could harm me in any way. I've been wondering so much about it lately that I don't want to have anal sex anymore because I'm worried.


What’s up with the acid in my throat?

1) I have had acid coming up my throat from my stomach for the last 3 weeks. It comes up and just burns my throat. What is it? Do I have an ulcer? By the way, I get 3 hours of sleep a night, and my roommate doesn't help the situation.

2) I have recently asked you about my would be ulcer. I shall pose the question again. Lately I have this damn acid coming up my throat. I've been under a lot of stress and have strange sleeping habits. I am also drinking a lot of coffee. I drink about 5 cups of coffee a day and my roommate isn't exactly stress relieving. I go to bed about 3:30am and wake up about 5:45am for crew. Am I dying? Do I have an ulcer? What's wrong with me?
