Some context. I never wear panties, ever, and have not done so for years. I often wear skirts and dresses, sometimes quite short dresses. I have had fun on nights out etc and people have noticed when we're having some fun but a couple of months back I was at an event where out of the blue the man next to me said "excuse me, i just want to let you know, it's quite obvious you have no underwear on". I giggled and said "thank you, I know" to which he said "I'm only saying because I don't want you to be embarrassed". It was hot, really hot and got my head racing, it was really kinky but it's got me thinking. Would you say something, would you say nothing, would you move away or would you try and keep looking. What would you do in that situation as a man?
