My wife and I and our daughter got ours pierced at the same time. I went first. Mistake! It hurts males MUCH worse than it hurts females, and they almost chickened out after seeing how badly it hurt me, and the blood running down my sides.
But when my wife went, no issue. Hers, after nursing three kids, were big and soft and supple, not leathery like mine. No blood, and really, no pain. So daughter went next. Grimmaced a little bit but not more than a "pinch" of pain she said.
Here's the tradeoff, though. Men heal quickly. I was pretty much healed and trading for posts in 6 months. But the women? Took nearly a couple years. And my wife got an infection nearly one year in.
Today... my wife and I have had ours done twice. Me because I took mine out after one got ripped out. See, men don't have bras to protect theirs. I had bent over to lift up a big cabinet in a cabinet shop I worked in and when I brought it up in sort of a clean-and-jerk move, it caught on one and tore it. Guy heard me gasp and saw my face, asked if I'd hurt my back. I said no, "But can you look around for where my eyeballs went? I think I heard one hit the wall."
My wife about the same time was tired of dealing with "migration." The things can go in perfectly horizontal and flat to the breast, but then in time "migrate": meaning they might come away from the breast, be a 1/8th to 3/16th of an inch up the nipple and have rotated weirdly. So she took them out.
A couple years later we had them redone. ANOTHER thing to think about!!! Re-piercing through scar-tissue is a whole other source of PAIN. But... we had them done, they've stayed okay, we're not ever taking them out again. Just that, I catch mine on things while I'm working, and the frickin' dog gets his claw hooked in one now and then. OUCH!
Other than that? Love them! Are they sexy, hell yes! And do we both like them played with during sex? No doubt!
