My boyfriend and I had sex this afternoon, and a few hours later I realized that my labia minora is extremely swollen, more so on the left side though. There is no burning, itching, or pain although it is rather uncomfortable feeling to sit or walk. During intercourse I did feel more friction than usual, but I've felt that before and never once had such an issue. I may have come into contact with semen and I don't think it would have been the first time.

I'm wondering if it could be a built up latex allergy, or maybe a semen allergy, or possibly just from the friction.

I just would like to know what the most likely cause of the swelling is and what I can do about it. If it doesn't go away soon I'm going to see a doctor about it. Thank you!
