Why can't I make my boyfriend org**m?

My boyfriend and I have been dating for 11 years and I have never made him c*m. Everyone says to pay attention to the head, but it tickles him when I stay there for too long. I think it would take 4 hours of constant sucking to get him to c*m and I just don't have the jaw power. Any advice?

Well what you can do first is start teasing him maybe start off my talkin a lil dirty to him then you might want to just slowly make your way to his pen*s don't rush it! and try slowly takin your hands and rubbing him all over his body!
