too much sex?

So me and my boyfriend are in college and and stay with each other most nights. He definitely has a higher sex drive to me and it just seems he wants it ALL the time like every night. I know we are young and we should be trying things out and whatever but Is this normal? How should I feel about this? We're young but we've been together for years and it can't be the only thing he wants from me but sometimes I just wish he could just cuddle me without trying something Because I just hate saying no to him.   I love him but I feel like it ruins things because I'm always the one saying no and it just makes me over think everything.
