What else could you possibly write to some stranger that you know nothing about except maybe 2-3 pictures? You'd have to at least put some hobby or interest in your profile that I might relate to... But just asking about something very specific as a first message also sounds weird. I really just wanna say "Hi" and see where it goes from there... What do women want?
