I started my period on Saturday but on Thursday I had sex with my boyfriend. We've been together a 1.5 years.

Well Friday I Strate have a burning sensation every time I would and still go to the bathroom. He's rather well endowed. So could it be he ripped me.? We didn't wait for much lubrication to happen...but kinda went for it. I'm clean from stds and so is he. We've been checked Before and then again at the beginning of the year. Should I see a doctor.?
