Sex life isn’t that great

So we have been together for 4 years and are engaged...just started living together last summer...before him I didn’t have many partners and I’m his first. I don’t get in the mood as often as him bc I mean sex really doesn’t do much for me anyway. But he gets in the mood fast and wants to get to the point fast too. We don’t do much forplay or anything. I mean I am rarely ever in the mood and idk if it’s just bc we aren’t good at it or are most women like that bc they don’t get off from sex? What should I do?
