He got nervous when he talked to girls when he was like 10. When he had his "crush" on Annabeth. He's definitely not awkward with girls in The Son of Neptune. And Nico already stated that he had a crush on Percy, but I'm like 95% sure he still likes him, lol. If you like someone then that's the only person you like. And he's young enough to have only had one crush, and since he was in The Lotus Hotel it's not like he'd remember a lot before that.
