"he was worried about the local neighbor boy stealing more of his garden shed tools than thinking about how to get any sort of action from him"

Although it's true that being attracted to someone doesn't mean you're only concern is getting action from them, above anything and everything else, it's also true that just because you like boys or girls or men or women doesn't mean you want to "get action" from ALL boys or ALL girls or ALL men or ALL women. Same idea of finding out your best friend is gay, and just assuming he wants to have sex with you. Maybe you're not even his type.
