It hurts 😳

Brie
Okay, sooooo I need help!
I'm 18 years old and have been sexually active with the same man for almost 5 months now. We're exclusive and have both been tested for STD's. I noticed in December that after we would have sex, there would be a tiny drop of blood in my discharge when I'm cleaning up. At first I was like "oh, I'm probably spotting..maybe it's my period?" It wasn't, but I did get it eventually. In January I started birth control, I've been on it for a little over a month now. But what I've been noticing is that I can't stay wet during sex. Even using lubricant, intercourse hurts, so does fingering from not being wet enough. I don't know what to do :/ and it doesn't help that he's quite above average..lol please help!
