[So, this is what I think their sexuality is (in MY OPINION) I’m not forcing sexuality on any of them, it’s just my way of seeing things]
Percy: Not 100% straight. (Like Josh Hutcherson; considers himself straight but if he falls in love with a guy, then ok he’ll date him)
Will: Pansexual (In my opinion all of Apollo’s kids are. I don’t know why)
Frank: Straight, kissed a boy once out of curiosity.
Leo: Straight af. Used to say: “That’s so gay” but stopped when Jason told him he was Bi.
