He won't fit?

Hey girls. So I just recently started seeing a guy a few months ago. We have fooled around a lot and have tried to have sex. But it just doesn't work. He seems to think my hole isn't big enough or wet enough for him. Which countless articles I've read have said that with enough foreplay that shouldn't be an issue. The problem is he can't keep a hard long enough to go through the foreplay required for me to get turned on fully. So we just end up trying to stick it in too early and it doesn't work. The only I see to fix the problem is by getting me turned on faster or getting him to keep a hard on longer.  Does anyone have any advice as to how to accomplish this? Or maybe other possibilities of what might be wrong?
