I've had unprotected sex yesterday, and today I feel sick, warm, tired, & nauseous. I am on the pill so I should be fine in terms of pregnancy.
My partner has complained about pain, feeling sick, and a change in his semen color which has only occurred today. He was tested a few weeks ago and was clean; I was tested months ago, was clean, and have been engaging in intercourse with him only. (But he, on the other hand, has been engaging in unprotected coitus with others).
He now believes he's contracted something from me (but as I said he is the only partner I have).
What could it be?
