I could see that unfortunately. I've had the unfortunate luck to meet people (both men and women but more women) that to call snakes would be an insult to the snake.
On a date though? Listen, keep an open mind, and cut bait if they do something that betrays your comfort zone. Avoid compromising situations, you don't know them, that's why it's a date. No matter what you have to open up and trust just a little, and recording for legal and training purposes just ain't that.
So imho, as a person that absolutely understands wanting help with social interactions and dealing with trust issues, I don't believe 99% men saying this is the reason they need the perve glasses on.
