My bf is very... rough.

So he is very... big in a certain area. Specifically in the circumference. It hurts bad. But I don't know how to tell him its overstimulating. I tried to explain to him that I need tiny breaks but he's so rough. It doesn't necessarily feel bad but its too much for me.

Update: I told him and he says he'll be gentler. My hole is in pain from those last few times so I told him to give me a break and he said okay. He's not as bad as u guys are imagining him. He's just a horndog :)
