Thoughts? 18+

I had a customer come in, who's a regular and just found out he was gay so we were just chatting about dating and guys etc. He was telling me about kinks and what he's into, (in a friendly way), but he kept like not saying one of the kinks. So eventually I just was like "Okay you have to tell me now cause I am curious." He told me and it was the like baby, little kink thing, I didn't ask much more of the extent. My thing is he told me he doesn't talk about it often since like people have bad opinions about it. As someone who like isn't into any kinks/fetishes what are your thoughts about it. Personally I do find it a bit icky but like i'm not about kink shaming. I also just need to stop talking to people at this point cause people love to tell me about there personal lives too much LOL.
