bleeding during sex

Lolo
Anyone else experience bleeding during sex?  We were having sex earlier then when I was about to cum he got real serious and was like we're stopping right now, so I'm like what's going on you're scaring me as soon as he pulled out I saw the blood. Went to the bathroom thank god there were no clots. But I'm just gnna take it easy and relax the rest of the day because I do have an appointment in the a.m. So not trying to spend the night in the emergency room
