My boyfriend had a rash between his legs, near his testicles. It did not itch, but it did have a stench. I did not put my mouth anywhere near him as this was going on. after about a few days, it all went away. we still waited a while to do anything, but tonight we finally did something. I gave him oral. Let me add, we have been together for four years. He ejaculated in my mouth, and after a few hours my lips looked swollen. They looked more red around the corners and around my lips, and feel tingly and chapped. could this just be ironic that it happened tonight? am I overreacting?
