Making me cum

Shannon

I need some advice on something that I think is weird and it's bothering me. My boyfriend and I will be fooling around he'll be fingering me and playing with my clit and I'll feel like I'm about to cum but I make him stop or push him away. Like the other day he was fingering me and i got the weirdest sensation like i was going to cum so I pushed him away.. I don't know if this is like a mental block or something. My boyfriend is bothered by the fact that he can't make me cum, but he always just says that it's something we are working on together to make happen. Can someone please help.
