Eh idk, my experience with the "male loneliness epidemic" is:
It's not just about "sex" (which it seems like that's all EVERYONE can focus on, so I get it,) but also about deeper meaningful connections. Personally, I have a few FWB, I want to fall in love with someone again, though, tbf, the part of me that had the ability to do that could also be dead, kinda hard to tell tbh.
It's also about (again, for me) the fact that increasingly it seems that the ONLY places acceptable to meet a woman you have not yet talked to are:
A) Online dating services that sell your data, are designed not to give good matches because they want you to stay on the app, and charge a fee for the apps to even be useful, and they're all owned by one company.
B) The bar. That's it.
Well, as for A, I value my privacy, and don't enjoy paying money to have horrible experiences. I run GrapheneOS idek if tindr would run. I don't even have social media, I can't stand writing my own bio and don't take selfies, it's not a good option for anyone but doubly so for me. Also I'm not Tom Cruise (or whoever you're horny for just sub them in) level attractive and as such I have to rely on my personality, which isn't really text and picture based. As for B, I do still drink but not like I used to, and even if I did I can't afford to go out as much as I used to in this fucked economy, and tbh meeting drunk women doesn't seem like a good idea anymore, feels like it opens me up to problems I don't fucking need tbh.
So where does that leave me? Well, common advice is to:
"Have your friends set you up with someone." Ok great. None of them have any single friends, at least none that have expressed interest in being set up with me, or that I am interested in myself. So, either "pray," or I could actively make new friends just for the express purpose of finding out if they have hot friends that want me, if not, move to the next friend I can find and try again? Sounds like a bad plan to me. I don't have the social battery for all that honestly.
"Go to the gym," you mean the place women complain about being hit on the most? Sure, that'll help, "idfk how to use this giant machine and I know you just watched me look like a giant idiot, and I know you hate being asked here, but I saw you from across the yoga mat and thought you had a cool vibe, wanna go out some time?" That's setting yourself up for success right there lol.
"Find a hobby," yes because when I'm not at work or sleeping I simply stand and stare at a wall. OF COURSE I have hobbies, but not only do "women want to enjoy their hobbies without being approached" also my hobby is hiking local trails and taking pics of (mundane to you but to me,) neat animals like salamanders and snakes. Idk if you guys are aware of this, but women would rather meet a literal bear in the woods than a nerd with a camera, I used to talk to people on the trails but now I just give them a wide berth (unless they're dudes, dudes are chill). Also like the library, but I'm the only one under 70 (well, and above 18, lots of parents with kids but that doesn't help me lol), other than the cute librarian I have a crush on (but you're not supposed to ask them out while they're working either, and also if she says no it'll now be awkward every time I go cause I'll feel like a creep, so she'll never know).
The real solutions seem to be we need a third place that is acceptable to meet someone and ask them out politely and take no for an answer, or women would need to start asking men they like if it's unacceptable the other way around, or I need to become gay because as I said earlier guys are chill, you can talk to them anywhere. Unfortunately we're actively killing third places and the ones still alive women complain about being approached, women so rarely ask a guy out and I don't think it's becoming more common, and afaik I was born unlucky on the gayness.
And I mean, am I "lonely?" Idk. I have friends, FWBs, kitties, I've had abusive relationships worse than loneliness, so "no" I guess, but also yes insofar as "I haven't felt real love in about 15 years and it'd be pretty cool to feel that for someone again," and I'll guaranteed never find it if I don't start doing the secret solution: Just say fuck it, fuck you, and fuck what is socially acceptable, just start asking out ANY woman I see/like ANYWHERE, politely and take no for an answer of course, but anywhere. At my job, at her job, at the gym, in Aisle 10, on the trails, fuck it. If I don't it seems my only option is to pray to a god I've never believed in that a lady falls in front of me like goddamn Rufus in Dogma and she happens to like me, and I happen to like her lmao.
