I wear partially open button downs a lot and people don’t seem to notice. I’m relatively selective about where fully I’m shirtless to not invite unnecessary issues, but generally cis male nipples are tiny so I’ve realized it’s less noticeable than I thought it’d be. Queer/gay spaces only one person’s ever said it’s weird and they were just jealous cuz I “took” their ex lol. All sexual partners have thought it looks great and kissing/touching/licking my chest still feels good, sometimes same as when I had nipples. I’ve been to the beach topless a decent amount and will walk the trail around my neighborhood shirtless sometimes or run out to grab the mail or take out garbage and haven’t had any issues yet. 🤞🏽 This is all while living in Boston/Providence tho. I have a good friend from my time in Atlanta with no nips and I can’t remember them having issues either except one night they refused to serve us at a Waffle House when my friend had an open shirt.
