I had sex with a guy that had a huge dick like 7 1/2 inches at least and he really rammed it into me. Since we've had sex I've been bleeding a little randomly and my vagina is extremely sore. It's the third day since and now it's starting to sting when I pee. The white stuff you usually find on your panties, like when you're ovulating, is now an off white cloudy color instead of my normal white. Someone HELP
