Hey! I've had quite active sex life. My partner and I have been trying to have anal sex for some time but I couldn't do it every time. It was always very painful. But last night we did it and we did it in missionary position. It wasn't painful but after that I was cold and I had fever. I took paracetamol for it. The fever is gone but Im just worried. If the fever and cold is normal or not? It's been almost 12 hours since I took the pain killer and the fever didn't return. Do I have to get myself checked or everything's fine?
