The ladies certainly aren't wrong in asking to be aware of it beforehand, or in it being an outright deal-breaker in the first place, but if you're going to do it, it is perfectly possible to carry an appropriately sized concealed carry handgun in a fitted, inside-the-waistband holster and take your damn pants off without it ever being seen and end up looking like Yosemite Sam. How profoundly uncomfortable and scary for them that it would ever even be an issue in the first place.
I'm a proud CC holding resident of Brownbackistan, but I've never been inclined to make a foolish enough choice about
who I was seeing or
where to ever feel compelled to carry into a session.
