it's not cute anymore

I started sleeping with someone who lives 70 miles away from me. Naturally, the distance makes it impossible to see each other very often. So when we do have sex, he tears me up so bad that I bleed for a couple days after. And yes, I'm sure it's not something else. At first, I thought it was like a trophy but now I'm getting tired of the pain. I can't wait til we can have sex more frequently so that my body will adapt.
