Turned on..?

So me and my boyfriend have experimented a little but it seems as if I am craving the feeling of his skin on mine. We have both agreed to wait for sex but sometimes I get turned on bad and he has to stop me. Its been happening for about two weeks and idk why. He is not a virgine anymore but I am and its like I'm scared to take a huge step and just do it but at the same time I kind of want to see what it feels like:/
