Do I sleep with him?

So I have been best friends with this guy for 3 years and we have always been there for each other even if we're a bit distant at the time! He's always said to me that he can't think of loosing his virginity to anyone else apart from me, which is really sweet! It would be my virginity too! We hung out the other day and we got cuddly but nothing happened and then I had to leave! We always joke about it and stuff but I just don't know what to do! I don't know if I want to or not! Like I want to loose it but I just don't know! Help me please 💋
