occasional bleeding during sex

[ECUgurl]

I have been with the same guy for the past 4 years.  He's the only one I have had sex with.  Pretty much from the begging I would occasionally bleed during sex.  I wouldn't bleed before or after, just during.  I have been on the pill (Trinessa) for about 2-3 years now, have had regular gyno visits that come out normal and I still bleed.  We can have sex one time and not bleed and have it again later on and I'd bleed then or vice versa.  It doesn't happen all the time and I've tried to see if each time I bleed, it's because we do a certain thing, but I don't think this is the case.  Any ideas as to why this could be happening?

i have had sex with my boyfriend many of times before but when we had sex tonight i started bleeding during sex. i'm due on my period but i don't think its that because i haven't had any signs of coming on. what could this be?

I haven't had sex in years now i found a mate that i been with sexually and the only one. The first time we had sex i notice after sex i was bleeding. This never happen in the past years so i thought maybe it was because i haven't had sex in years. But now i notice this happen everytime we have sex. Should i be worry?
