Burning and bleeding after having sex.

I have had sex with my first guy for about 2 months now. Lately the day after sex, I have a very uncofortable feeling. We use a condom all the time. When I go to pee, it's painful and burning, just a little urine comes out and its it light pink color on the toilet paper. I had this problem for about two - three times now, and I am getting worried. The whole thing goes away next day, but is it normal? I have read that this could be some sort of injury of the. Vagina, sometimes it hurts during the sex, and he does go pretty deep, that I have to stop him sometimes. Could this be the reason? Please help, I am getting really worried.
