kink i cant share with partner

i have this secret kink, something a bit taboo really. ive never told my boyfriend about it because hes just... well different than me in that way. so when i got the chance to try it out recently at an event for folks who enjoy similar things... im not sure what to make of how good it felt to let go and explore without any judgment from someone else. its a bit overwhelming now, wondering if this is normal or if there's something wrong with me. has anyone experienced this kind of thing?
