What is wrong with me lol

Okay so I’m a virgin and I love the idea of sex like I think of it I’m like hell yea and I imagine me I’m like hell yea but when I actually think of me doing it I’m like no thanks I think I can wait for a while I don’t want to, like I feel I guess uncomfortable with the idea of me actually doing it but the idea of all of it I love. Is there something wrong because idk what this means😂
