About a little over a week ago I let my boyfriend face f*ck me. It was really rough and he came in my mouth. I've never had a guy do either. The cum left a burning feeling at the back of my throat after wards.  It's been a week and my throat/ mouth is still sore. I don't have any redness or irritating nor do I have any bumps. He claims he was recently tested for stds. Should I be worried or is it normal to have a sore throat after a rough time? Please no hateful comments. I'm 19 years old and I've been very sheltered in a southern/ tradition and religious household. I don't have anyone to talk to about sex and I'm knew to being with someone like this. Please help
