Ok, I'll give my story.
I was at a club in downtown Houston when I was 19. I went with two hot female friends.
I got tired of dancing so I strolled over to a quarter pool table in the corner and start shooting by myself.
This guy comes over after a bit and tries to hand me a blue drink (that should have been my first clue. What straight guy drinks blue drinks? And who buys drinks for other guys they don't know?) I tell him no thanks, and he starts making smalltalk. I realize after a bit that this guy is standing entirely too close to me and keeps trying to give me the drink. You know the way we men look at women with that "I am mind fucking your tits through your shirt" look? I was getting that, aimed lower.
I was pretty young and naive at the time and kind of freaked out. Thankfully, one of my friends sees me and comes and grabs me to go dance.
Not that it matters, but as soon as we got out on the floor the song changed to Pussy Control by Prince. We laughed about that for a long time.
Now, with age, I would not be freaked out. I'd probably laugh and tell him he's barking up the wrong tree.
