Hi, during sex last night, my partner split the vein in his penis, we were not aware of this straight away, only when changing position, did we realise there was blood coming from one of us. We realised it was from him. However I am concerned, as there was ALOT of blood coming out of me and in me. I tried to clean it out as best as i could, but even this morning, there still seems to be more blood in me. Could this be harmful to me? What should I do? He does not have any sexual diseases.
