The reason he talks about Jason so much is that while Jason and him are friends, Jason is the son of the king of the gods, has the awesome powers, the looks, and he gets the girl. Leo on the other hand has a better personality IMO, but he sees himself as the lowly mechanic in comparison to Jason. To a certain extent, he feels the same way toward Percy, Frank, and Annabeth. The only one he really doesn't feel weird around is Piper because he likes her as a friend (as she isn't really his type). If I had to guess, his fatal flaw is that he always compares himself to others. I mean with Narcissus, he sees a guy surrounded by girls that would do anything for him, but Narcissus doesn't care about them. He is like an opposite Leo, as Leo cares about other girls, but no one seems to like him for whatever reason, so of course he would describe him in more detail. However I don't think he is gay as his hopes when building the Argo II were to gain the respect of the other demigods and maybe even get a girlfriend. The way it is written, it doesn't sound like he is being shallow and just hiding things, but truly wants a girl to share his life with.
