Male gynecomastia... I am curious.

Maybe because my husband gained weight... my chest... ㅠㅠ

I don't usually pay attention, but I am so concerned that I am looking into gynecomastia.

Did I gain weight, or did my chest muscles become more prominent?

Or maybe I originally had some chest muscles... I'm confused.

Should I call it a nipple? It's not like a woman's protruding tip, but still, it seems big...

Should I also inquire about this with dermatology or plastic surgery?
