the vaginal area is very vascular and can bleed with minor trauma. sexual intercourse can create just enough localized trauma to cause light bleeding. this is no more concerning that a minor nose bleed when you have a cold but if the bleeding is severe or intercourse is unusually painful it would be best for you to be examined by your medical provider. it is not unusual to find small tears (fissures) as a result of sexual activity.
can a guys large penis make me bleed lightly after sex? . until yesterday i have not had sex for over four months and the new guys penis is significantly larger than i've ever had. . we used a condom. and it only lasted a few minutes because we did some foreplay earlier and he came within a few minutes. it hurt because it felt like my vagina was stretching (obviously) and when i got home i had to use the bathroom and when i wiped there was a little blood. it is. very. light. not even a flow just a few drops show up when i wipe.
