Sex scares me

I’m a virgin and all my friends have already lost their virginities... I started talking to this guy and we plan on having sex but the thought makes me terrified. I’m scared of getting attached because I don’t even know what I want from him, I feel so stupid for even thinking I could handle being in a fwb situation but at the same time I want to do these things... UGH WHAT DO I DO

boys are so confusing and I don’t understand how to have sex... and I might lose my virginity this weekend...

This is a mess of a post I’m so sorry
