Honestly - the more I'm learning about this market - the more I'm thinking we need to launch a line / brand marketed just for men. The more you know!

I wonder if it's the marketing or if it's just men that are into feminine stuff. Will running commercials playing industrial rock music and starring big burly construction workers wearing pantyhose like it's badass really sell?

Probably you should just keep the marketing low key and just add extra space in the crotch area for the balls.

For men they're called base layers - like long johns but made of thin nylon in manly colors.

It's already been done! https://www.wikiwand.com/en/Pantyhose_for_men

From our conversations with customers so far, I'd say its mostly men buying for their wives/girlfriends - but quite a large number buying for themselves as well.
