Help pls... first time

Feeling a wee bit conflicted right now ...

So I’m like rlly ready to have sex, like I’m ready to do. But idk if I want to be in a relationship or just like a one night stand ( bare with me )

So I feel like if it was in a relationship it would be too much of a big deal and I don’t rlly want it to be.

But if I did like a one night stand kinda thing idk if I would feel to like “attached” to the guy like ( idk if that makes sense)

So the situation is that I’m going to be at a party next week and there’s a guy I got w before. Last time we were gonna do it but he didn’t have any protection so we didn’t. But then I was like thank god cuz I wasn’t ready, but now I am like. I don’t think I want a relationship w him, but I do like have that kind of attracted to him

So basically yea.... help

Side note - Im16 nearly 17 and I rlly want to have sex before I’m 18
