Am I the only one ?

Honestly I tried having sex one time and I just wasn't into it. I wasn't in love with him so maybe that's part of it , but it just felt so awkward, and it hurt. Since then I've been super skeptical about having sex with anyone else but I see everyone post on how good it is. Recently Ive gotten pretty serious with this guy and he's asked if I'm ready to have sex and I honestly don't know. Any tips ?
