...I Think I Might Be Bi-Curious Now That I'm Out of My Long-term Relationship

So...here's the thing. Ever since my long-term relationship ended a few months back, I've been struggling with this weird feeling deep down that maybe there's something else out there for me besides just straight sex and dating women again. I know it sounds crazy, I mean, all these years of being in one monogamous relationship with Mary...and now, well, after we split up over irreconcilable differences, here comes all this new stuff bubbling up from the deep dark corners of my mind... It started with just little things, like when I was watching TV and saw some guy flexing at the gym or shirtless in a commercial. And honestly, there'd be this flicker inside me that would almost make it seem like...well, maybe I should have paid more attention to those old ads for gay porn back in college. But no way right? I mean, we're talking about my life now, there's nothing bi-curiosity or anything has to do with it... Then came the internet part, after a while of feeling lost and lonely after the breakup, I started browsing through some new social media platforms just to keep busy. One day, out of boredom, I clicked on a dating app geared more towards kinks and...well, not exclusively straight stuff. And oh boy, that was quite the rabbit hole... I ended up chatting with this guy who seemed nice enough, very polite actually, and we talked about all sorts of things without ever getting too personal or graphic right away. It felt okay for a while, but as he began asking more direct questions about kinks and preferences... I just couldn't bring myself to answer honestly. So, we drifted off into another conversation... It's been bothering me though, that moment where I had the chance to open up and instead chose not to because of this nagging doubt if I even want to explore those feelings in real life. Or am I too old now? Has my life passed me by with no room left for change or growth? So...here's the confession part, I think I might be bi-curious, but I'm scared shitless about admitting it out loud and taking any kind of action based on those feelings. What if I screw up everything with potential new relationships? What if this whole thing goes away when I'm done thinking about it too hard? Sorry for rambling...but you know how it is when life throws a curveball at your identity and makes you question everything you thought you knew about yourself. Thoughts?
