DO some men call a woman from No Caller ID just to hear her voice or something?

I got two calls at 3.00 AM and it was kind of creepy but I wonder if it might be a guy who likes me? Like this married man who flirts with me and checks me out but he hasn’t made a move. Would men do that? Have you ever done that to a woman you liked? I didn’t answer by the way and usually if it’s a spam caller I can see the number from the Czech Republic or something..
