Am I overthinking?

So, my boyfriend has had more sexual experiences than I have. I've never given head, he's given and recieved. I never had a one night stand, he has. I've never showered with anyone, he has. He's has more sexual partners, I've only had one. I haven't had sex and done any sexual activities with him yet. I know I shouldn't be jealous or mad about his past but it kinda makes me insecure. How can I get over it and should I tell him I feel? I don't want this to become a problem and I know I shouldn't worry about it, but it honestly bothers me.. What should I do?
