I haven't had sex in about 2 months and recently hit it off with a new boyfriend. We had sex and it was enjoyable at first, but I started to get dry after awhile and kept going so he could get off. It started to get immensely painful and had to stop. This would continue several times in a row and then I just wouldn't be able to continue. To use the bathroom, it burns really bad and the urine was very yellow and strong. The next day I started spotting even though I'm not due for my period for another week at the least. Is this anything that I should be worried about or did I just go raw from prolonged sexual intercourse while dry? Help please :-(
