Can anyone help me?

What's the best way to ask someone you want to do more foreplay with? I've had a hard time asking him. He hasn't given me an orgasm and I really want one. I don't know how to do it to myself. Also mainly for some reason when I finger myself I cry just as soon as I stick my fingers in there to touch the g spot. Only for few seconds and I cry. So I gave up on trying to do it to myself. He has gone down on me but not long enough for me to actually orgasm it's y frustrating. So how do I ask him without being all awkward about it?
