I’ve never regretted getting my nipples pierced. I like that they’re low key most of the time but semi hardcore when people see them. They provide a kinky addition to sex/masturbation, and a punk rock emotional boost when I catch my reflection after a hard day.
And to answer a few questions for those here who have so many..
Yes, you have to clean them, but only intensively for a few weeks to a few months. After that they mostly take care of themselves, unless you’re having persistent problems, which does happen. Different piercings act differently.
Yes, snagging is an issue. I’ve moved to open rings after a couple close calls and haven’t had a problem since.
No, I’ve never had a problem at airport security. They’ve never said a word.
Yes, even in my forties, they look awesome to me.
