Here we go... This is really embarrassing, and I would rather not talk to my doctor if I don't have to. I am 20 years old, and in relatively good health. Four days ago, I was in the restroom at school an somehow I got some #2 in my vagina. Since I was in a public restroom, I couldn't walk out and wash off, so I flushed the toilet, and dipped some toilet paper in the water to clean myself off. I mentioned this embarrassing moment to my boyfriend and he grew very concerned. He was worried I could have gotten an STD from the water. I wasn't sure that was even possible, but after a little online research, I decided it wasn't a problem. Then sex started to hurt a little bit. Yesterday and today we had to stop because it was hurting me so much. I don't know how to describe the feeling. I have had painful sex before, but this is very different. It feels almost dry, but I am not totally dry. There is a slight burning sensation at the opening of my vagina. It only hurts when he is moving inside of me, as I the friction is causing the pain. I do not have pain when we are not having sex. There is no blood or anything in my urine. The only other factor would be that I have had many urinary infections- I read online that painful sex could be linked to this. I am so confused and worried. What is going on here???
