Opinion on 18 y/o and 25 y/o hooking up?

I'm 18 years old and haven't had much in the way of a love/sex life thus far and I don't want to wait any longer... I've had a huge crush on a boy (my age) for like two years but he has a girlfriend and there aren't really any other boys my age that I'm interested in... So, there's this drop dead gorgeous twenty-something (like mid to late twenties?) man at the place I go ballroom dancing and he and I always dance quite sexually and I'm crazy attracted to him. There's also a super sexy model-looking guy in his early-mid twenties who just started working a short-term job at the office at my school. Obviously it's not illegal, but is it a bad idea to hook up with someone significantly older/more experienced sexually than you are? Or is it a great idea? Help me please 😝
