Does anyone else have this problem

Nikita

I have a concern, i just started being more Sexually active after not having any sex in 9 months. Now it seems like everytime i have had sex. Which has been one every couple weeks. I bleed after being intimate. I am starting to get a little concerned. I have seen my gynecologist a year ago. They didn't see any problem with anything. Does anyone else have this problem? What could it be?
