Sunday I had a careless hookup out of the blue. We started to have sex and when he went into he kept hitting a spot deep inside that HURT. Like, a slightly dulled sharp pain. I thought maybe it was because he was going really deep. However, I tend to usually enjoy deep, rough sex and be okay with it. And yesterday and today there is still lingering pain in the exact spot that hurt when he hit it. I feel it most on the stairs or when using my pelvic muscles to sit up. I do feel it a little just sitting. I also have a thick white discharge. I'm not sure if this is something that I should check up on, if it is simply because of the sex, or could have been from something else and the sex brought it to my attention.

Any thoughts on this would be appreciated.
