Too inexperienced?

I’m 15 almost 16 and a sophomore in high school. I have been getting a lot of interest lately from guys who are older than me. I’ve hooked up with 2 senior guys but they didn’t try anything on me, but recently this reaaallllyyy hot junior guy asked me to hangout and I know his intentions are to basically do everything besides the literal act of having sex... even though he really wants to have sex with me I told him i wasn’t ready for that. I’m totally conflicted because I’m super nervous to do that stuff because I know he has done it before. I really wanna hangout with him because he’s a cool guy and again. he’s really hot. I just wanted some opinions on what I should do! I know I’ll have to do this stuff eventually which is another reason why I want to go. Please help!😩
