Not impossible; most just are looking in the wrong places.
Finding people online works exactly the same as it does offline - you meet people in places of mutual interest or activity. Just like how IRL you would meet people in a local coffee shop or community space, you do the same online too. One of the biggest mistakes people make is thinking the answer to this problem is a dating app which are literally designed to keep you hooked while making sure you don't get what you're looking for.
Find common interests. I found a chat server that reflected a social interest for myself and joined. Met a group of people that were fantastic and met them through that. Results may vary though as this was in 2020.
My advice is don't look to date but to find a connection through other means and / or interests. IMO, people who focus on "dating" often don't express themselves which is what most people use to ask: "Is this person a friend or foe?".
Phrasing matters. Men are adults girls are children. That may not be your intention but try to be mindful in how you interact with others and you may have more success with relationships.
Talking about men wanting to have "relationships" with girls carries the connotation that the men are much older, to the point of being creepy, or even that the girls are underage.
really? I've managed it a few times and it honestly wasn't all that hard. I moved one of them in with me for a bit due to an extreme life situation they were going through.
I met my late wife on Match.com in 2011 and we had a wonderful marriage. After she had passed away, I took some time to myself, but when I started dating again, I tried a variety of sites.
Hinge, bumble, tinder, and match all got me dates, but I eventually met my now girlfriend on match. We've been together over a year now and marriage is in the future at some point, we're just not in a rush.
It's worked for me twice now, so I think saying it's impossible isn't necessarily true. A lot depends on your location, interests, etc, but if you keep at it, you're likely to find someone eventually.
Perhaps post your online profiles, or portions of it, to some dating advice magazines and get some feedback. Without more information, we can't know why it's not working out for you in particular, but regardless best of luck out there!
It's clearly not impossible since any number of people do that every day. I'll grant you it's frequently an exhausting, somewhat dehumanizing, lopsided chore to deal with, relentlessly shittified by profiteering assholes with conflicts of interest, though.
If women can get dates with men online, then men are getting dates online.
But it doesn't really matter what other people's experience is, or what is possible. If you aren't having a good experience, go out in the world, meet people, make friends, you meet people who know other people, you'll find someone compatible but also make friends not just one romantic partner.
