hahaha. yeah. Im mainly thinking of nipple piercings getting caught on my bra itself. I have quite a few lacy things, & i the heat of the moment, or when im in a hurry to get dressed/undressed & im going out, i can see some issues arising there.
+ when im at home on my own, i don't always wear a bra, i don't wear one to bed, But i do wear one of those tops with the support bra thingy in them. But those are the only issues i can see with it, + if your partner has one as well, you don't want to get hooked on one another hahahah
