The Big Bang

Hey ladies, my boyfriend and I have sex quite a lot but when he eats me out which he is really good at, he can get me to the point while fingering me at the same time that I feel like I'm about to orgasm but then he either gets tired or cramped because it takes him so long and so much work for his jaw, or it just won't happen šŸ˜”
Any suggestions on what he could do or what I could do to just tip over the edge and reach my orgasmĀ 
Please help, am I the only one????Ā
