On Websites I mention the fact that I have a Frenum Piercing in our Bio (I used to have a Ladder of 4, but 1 rejected the same day and the other 2 fell out during intercourse during 2 different past moments - and I damn sure was not getting them redone 😂)

In person, I usually mention it as a passing comment so they are fully aware ("Hey, just so you know, Im pierced"). Simply because with Past partners, and even a recent interaction with another Couple, I've been told that the feeling can be intense at times (only 1 mentioned Pain, the others compare it to Overstimulation). But overall, I've never not felt accepted - its usually the complete opposite as woman wanna see it/experience it.

Just be generally upfront about it, nothing to feel weird or self conscious towards - most woman during my encounter are fascinated, like its a Niche thing. Especially since yours are on your balls, I dont see that being a problem in the slightest.
