My team mate will ask every man on the team for help before he'll ask me.

My team mate will ask every man on the team for help before he'll ask me. I've just been promoted to team lead, and my current team are all men. One particular person (Mr A), has worked on my team for a few months, and works on an opposite timezone to the rest of us. Our previous lead would stay after hours to help this person out. He was great but made people overly reliant on him. After he left, Mr A was Very distraught... he doesn't like change. I wasn't sure how to navigate this, so I had one to one chats with him, and assured him that I'm here if he needs anything. He seemed receptive.. however, I've stayed behind to connect with him almost everyday since, and he never asks for help. In fact he just pretends to "make tea" and doesn't return...!!! However, if another person is around, our manager, or another person on the team (a man), he will bleed them dry for advice and not let them leave. I don't know what to do? He's already quite sensitive so I don't want to storm my way through an interaction, but at the same time it's quite insulting that he'd rather go to someone else. Also not sure if this is a cultural thing, as he's mentioned he's not used to being with women in the workplace...? Maybe he just doesn't know how to rely on a female leader? I really want to develop my leadership skills. Any advice on how to get past this would be greatly appreciated!
