Feeling selfish

I want my SO to make me squirt. He's come very close while we were having sex (we have sex frequently and it's wonderful) but when it's him inside of me I stop myself. 
Aaaand frankly, he's awful with his hands. He just doesn't know how to finger me, and I want a good fingerfuckin! I feel really selfish, but this is something I feel like I need and I don't know how to say it in a way that won't hurt his feelings.. I don't want anyone else, I just want him to try harder. 
Also, I know I can because I have before. Just not with him.
