Love!!! AHHH

I need help. I haven’t hooked up with someone in three years and I feel like I don’t know anything about how to do things anymore. I’ve been talking to this boy for 6 weeks and we want to start doing things next week. But, I’m nervous because he’s hooked up with multiple people and has even had sex before. I just don’t know how to go about this. Am I good at sex? Do you have some advice?
