I am 50. Male.
I have never, ever, had a woman spontaneously start a conversation to ‘flirt’. No conversations except transactional ‘business’-type ones.
Only recently have I learned that sometimes women ‘make the first move’ and approach men. Even when I was younger, I would always be the one to initiate any flirtation.
Apparently, I am not now, nor was I ever, ‘attractive’.
