HELP! What should I do?

Me and my boyfriend have been together for two years now. I can currently in 11th grade. I feel guilty because I look at other boys and find them so attractive. I feel like I’m missing out on the highschool dating experience, and experimenting with different people. My boyfriend is so sweet he’s perfect for me and knows me so well and helps me with my anxiety, but I don’t feel how I did in the beginning of our relationship and I don’t know what to do. I wish there was a way I could kiss a few dude then come back to him but that’s not how it works. Help!?
