Divorce and My New Secret...

Since my divorce last month... I've been exploring something new with another woman from a dating app. We met up a week ago at this cozy hotel, both of us consenting to an affair-like weekend getaway for no-strings sex. It was all so planned and calculated... but when we got there, she surprised me by saying she wanted to try anal too. Initially, I felt unsure... hadn't tried that before. But then the moment came, her fingers preparing me, and it turned out surprisingly pleasurable... Her eyes were full of desire as she watched me respond. We've been texting about a follow-up soon, but now there's this weird mix of anticipation and guilt nagging at me....
