...and then I did it anyway...

I never thought I'd be one to go this far, but here I am. My partner has some pretty clear boundaries and we respect each other’s limits in the bedroom. But lately, there's been this little voice inside me saying “what if?” What if I tried just once... what if it felt good? So, last night, I found myself at a local BDSM club where I knew nobody would know me. I picked out a submissive outfit and waited for someone who might be into something taboo, like, really taboo. And he was there... He had this air of mystery about him that sent shivers down my spine. After some heated negotiations about limits (the right kind, no worries), we ended up in the playroom with blindfolds on and a collar for me. I was so turned on by the idea of submitting to someone like this... The sensation of his hands guiding me, touching me in places that only he had access to at that moment, it was exhilarating. When he finally removed my gag, we both came hard from something more intense than anything else I've ever experienced. I know this probably sounds crazy and I'm not sure what the hell I'm thinking. Should I tell my partner? Can I even look him in the eye again without feeling guilty? Am I just being rebellious or is there really something to explore here? Anyone have thoughts on where to go from here...?
