My girlfriend and I are and have been having unprotected sex for months now and Iknow I don't have any sexually transmitted diseases, but whenever my sperm is inside of her it is causing a severe burning sensation in her. I am not sure what's causing it. I use to drink grapefruit juice a lot and thought that was the cause of it, but I since have stopped drinking it over the last two months, but the burning still continues from my sperm, what could be the cause?
