Is sex really that important?

So I know what you’re thinking...hell yes it is!!!! And trust me I love sex, probably more than the average person but I think I love this man more. I met the perfect guy, he’s such a good guy like a REALLY AMAZING, SWEET, GENUINE guy but...he won’t sleep with me. We’ve been together for a while and every time I put myself out there we will get hot and heavy and then he will stop. He says he overthinks everything and is so nervous. He’s not a virgin, he actually had a lot of casual sex in the past but says that with me it’s different cause he actually cares. Now my question is, what should I do? Keep trying and get “rejected” which is how I feel or give up and move on? Is perfection really perfect if I have to sacrifice? But then again; is it real if you didn’t have anything to compromise? Please give me some advice...
