You asked for an update, so I'll write about what's happened and, more importantly, what I've learned over the past couple of years.
My sex life/relationship status has stayed the same, but to be fair, the lockdown madness was only beginning when I wrote the first post and for the past couple of years social life was very restricted. There was a long period of time when I didn't even go to the office since everyone was required to work remotely.
On a positive note, I seem to be getting more attention from women (interested looks, smiles in public etc.) than I've probably ever gotten in my life.
I still maintain an extremely strict workout routine and diet, going to the gym 4-5x a week, counting calories (I enjoy doing that) etc.
I've also experimented again with online dating and swipe apps, and even though I get some attention there, I haven't gone to any dates via those apps because the women are so far below my own level. It seems that online has gone downhill rapidly - almost as if all the normal women left the apps and only the delusional ones are left. I'm not going to waste any more time online dating.
I've also decided that I'm not going to actively pursue women because that mindset makes me miserable. Instead, I will keep myself fit, dress nicely and spend time in environments where I'm comfortable (office, gym, restaurants, coffee shops, libraries). If I see a girl I like and she gives me attention, then I will try approaching her. But I will not force it and I will have to accept that there is a high probability that I will remain permanently single.
Interestingly, a couple of colleagues have fathered their first child in their mid-50s (the woman being in her 30s). I'm still almost 20 years away from that, so I guess anything is possible.
Regarding sex life, I have realized that the best sex I (or most men) will ever have is with high-end escorts. The best ones have a model-tier body and treat you very nicely. They are very expensive and I've started to think that I'm lucky to afford them regularly. It's not always easy to meet the one I like the most because she lives in a different city, but I try to meet her or another one once a week for a few hours of private time. Sometimes go on a mini-vacation with her.
The most important thing I've realized over the past couple of years about women and dating is that most women are not that interested in men (Aaron Clarey has talked about this a lot recently). It is clearly visible now at work with many women remaining single in their 30s and 40s. Some of them have had children, but dumped the guy afterwards.
It really seems that only a small portion of all women actually like guys, as in wanting to spend time with them. To me, this is an epiphany, because it means that pursuing most women is a waste of time and no matter what you do is going to make her like you that much. This is the most important lesson I've learned over the past couple of years.
