Sex drive

I’m 22 and I have a high sex drive but my boyfriend who is 24 doesn’t. I lost my virginity to him less than a year ago and I’m tired of initiating sex. Every time that we do have sex is usually all about him and doesn’t make the effort to make me finish. I’ve told him this before and it’s just one little aspect of our relationship. He is such a great guy and we love each other very much and make each other grow as individuals. It’s just frustrating, I want to experiment and experience this aspect of my life but he doesn’t. Any advice?
