I've done the whole Dragon mating season before in stories, Issei would be very dangerous to be around if he did enter a mating season. Dragons tend to dislike males of the same species or other and in a hormonal state like mating season they would become rather aggressive towards males. Issei could end up hurting or severely injuring any of his male friends.
