My boyfriend is quite large. He's I think like 7.5 inches length which is fine, but he's extremely thick. Honestly, I don't like it. It fucking hurts and I'm not one of those guys who enjoys being fucked by a ginormous dick. He's been able to get it in all the way, but he can't thrust because it's too painful for me. Does anyone have any tips or tricks or perhaps a way that over time I can get more and more used to his size?
