Hi to you Mom and a warm welcome to the forum.
It is possible that you may very well have a problem here - although he's very young, your step-son sounds as if he has a narcissistic personality. Which has very little to do with his "being in love with himself" (in accordance with the legend of Narcissus, who looked into a pond and fell in love with his own reflection) and everything to do with a sense of being "special" to the extent that he's entitled to being treated as "special".
This sense of entitlement, and disregard for other peoples' feelings, can be very difficult to live with. It sounds as though his biological mother was his "foil", who literally mirrored and reinforced his sense of importance. It could be difficult for him to no longer have someone playing this role and you can anticipate plenty of attention-seeking behaviour.
My sense is that your step-son's sexual orientation is not the primary issue here - his narcissistic personality may make him prone to being flirtatious with men as a form of attention-seeking behaviour aimed at affirming his own sense of being "special" and desired.
