Do you think there can be pleasure in pain?

So, I’ve been talking to my boyfriend about buying some leather/BDSM stuff from a sex shop and got me thinking about how far I would go. I mean I find harnesses, cuffs, blindfolds, even slings and whips, I can see the appeal, I can imagine a sort of heightened sexual experience. However, got me thinking I could never do the full mask or latex outfits where the person almost gets reduced to some holes. Maybe because I have a boyfriend, I value the intimacy part and would feel quite offended if my boyfriends wanted to see no noticeable features of mine haha. What do other people think? I’m really interested in how other people see it.
