Hmm. I guess I don’t really have any strong opinions on nipple piercings, unlike some other piercings (I love pierced labrets, for example).
I think they can look really cool. There are lots of porn stars in the queer porn industry with pierced nips and they can look super hot. I guess I just wonder about the logistics of receiving nipple pleasure after having them pierced. I don’t think I’d ever get mine pierced because I wouldn’t want there to be anything in the way of my partner’s tongue/fingers/whatever. But I don’t really have any experience with pierced nips so I’m sure it’s easier than I’m imagining.
When it comes to piercings, I say just do whatever the fuck you want. I don’t share my parents’ aversion to body modification. But I do think that you should talk it over with your romantic partner, if you have one, before getting a piercing that will impact their sex life (e.g. your genitals, nipples, or tongue). That seems fair to me.
