Post-Breakup Self-Discovery

So I just got out of a relationship with this girl named Mia. She was the one who broke it off, and to be honest, there were warning signs... But damn, she was fun in bed. And that's where I'm at now, trying to figure myself out as a single person again. You know how after a breakup you kinda feel like half of your life is gone? Yeah, well, Mia always wanted me to take the lead and it's been tough finding my footing solo. We used to spend weekends doing all sorts of kinky stuff. She was into... let's say exploring different scenarios that kept things interesting. One weekend, we even tried out this dungeon in town where they had all these BDSM setups. Mia liked playing both top and bottom, which was wild but fun. It pushed me a bit, but I enjoyed the challenge. Anyway, here we are. A week after the breakup and she's my ex and I'm trying to figure out what I want from sex now that it’s just about me again... Last night, I woke up with this intense need. No real plan or anything, just wanted some release without having to worry about pleasing someone else first. So I started off with touching myself in the shower, imagining Mia's touch and how she liked it when I went a bit harder... Soon enough, that wasn't enough. I wrapped my hand around my cock and started stroking it slowly at first, just remembering her face during our last time together, those moans, the way her body would arch up against me. The longer I waited, the more urgent it got inside me. I grabbed some lube from my nightstand (yes, always a good idea to be prepared) and added that in for extra slickness. I started jerking myself faster now... My balls were drawn tight between my legs as I gripped harder, feeling that intense build-up start to crest. Just before the edge, I leaned back against my pillows, spreading my thighs wider open. Took one hand off to pinch at my nipples, Mia loved playing with those when we switched things up... And then it hit me like a tidal wave... Cum splattering out over my stomach and sheets in big spurts. Panting hard through the rush of orgasm... I wiped myself clean afterward, feeling strangely liberated and free for the first time since Mia left. So there you have it, just another day trying to figure shit out as an adult after a breakup. Am I being too selfish? Should I be diving into new things already or take some time alone first? What do you think...?
