Tangled Up In Knots (...Again)...

So here's my story... Me and Alex have been together for about three years now. We had this really great thing going, funny, sweet, all that good stuff. But lately it’s kinda gone sideways. You know how it is... we started arguing over the little things, then the bigger ones. I mean... sex became a big deal too. I remember one day, out of nowhere, I suggested trying something new in bed. Not like anything crazy or taboo (we're not into that), just switching up what works for us and seeing if we could spark some more chemistry again. It started with role-play, me as the boss at work and him as my employee... things got a bit heated fast there... But it didn't really fix things... We still fought, but now about stuff like this too. One night, after another big argument, I woke up feeling desperate to make something happen between us again. So I went into the kitchen and poured myself two glasses of wine, hoping it would loosen me up. I walked back into our room with the glasses, and we both stared at each other for a moment. He seemed unsure... I handed him a glass and just said: let's pretend nothing else matters right now. Let’s just go wild, no more talking about who does what around here or whose turn it is to do laundry. Just pure sex. No inhibitions, no stopping... It was incredible, he started with my neck, hands running down my back... I kissed him deeply, pulling his shirt off as we fell onto the bed together. The kiss went on and on, my tongue exploring every inch of his mouth while our bodies tangled up in a way that felt so familiar yet excitingly different... Hands slipped under my clothes, fingers finding me wet already... We didn't wait for anything else, no foreplay, just straight into the thrusts. His cock inside me from the get-go... it was rough and intense, both of us lost in the moment, moaning loudly, hips moving together like we couldn't help ourselves... When he came, it was with a groan that I knew so well, deep breaths catching his chest as he rolled off to my side. The afterglow was intense... but it didn't solve anything. So here’s what I’m asking you all: am I the asshole for wanting sex without boundaries and ignoring everything else when things feel bad between us? Is that just normal or is it a sign of something deeper? What would you do in my shoes? ...
