As a man (early 40s), this is what I found hard:
I am perhaps one of the few guys who actually thought about who I was swiping on, including reading the profile as well as the pictures. And also took time to send a decent message picking up on something interesting from their profile, along with the like (when able, e.g hinge vs tinder). But still sent a lot of likes I'd say.
Also I'm told I'm attractive, in shape and have nice photos (maybe a bit marmite physically, tend to either get 'absolutely gorgeous' or 'meh, not for me').
And yet I got so few matches. And even when I did, struggled to get a response to my opener (my text game is probably a weakness - much better in person). I assume (having seen female friends profiles and just how many likes they get) that my matches had so much choice, it was hard for me to stand out. I blame the indiscriminate liking from the guys here btw, not your fault. And it's not like I was only trying to match much younger; was searching maybe -8 through to +2 my age.
Whether it's true or not, I found the stat that the top 10% (or something) of guys (looks wise) get 80% of women's likes interesting. Exacerbated by platforms algorithms I suspect. Even if I'm not miles off being in that group, I'm definitely not in it.
So I loved loved loved it when a match messaged me first, esp picking up on my profile (so so many 'hey' and 'how are you's on bumble). Try it! You'll stand out.
However, what i found easy:
I was lucky enough to cut through often enough to get dates (i was always keen to meet quickly rather than pen pal). Almost every first date then went really well - even if there was no chemistry for them, they'd often be up for friendship because we got on so well and I now have some great friends this way. The amount of times I heard 'wow, what a refreshing change to meet someone normal!' from them about me:
Based on their experiences, OLD for women 35-45 is dire. So many weird guys with baggage, or they're players. Whereas every single woman I've met has been lovely, and well, normal, even if there was no chemistry for me. And often the break up of their marriage or LTR was because of an abusive, cheating and/or emotionally unavailable partner. Fortunately that wasn't the background to my break up - still friends, very amicable, kids 50/50, grew apart (no cheating), so probs easier for me to stand out.
So overall, I'm convinced the pool on the women's side is so much lovelier than on the guys side (not always, but overall). And that's why it's so depressing for you all. And overall, I count myself lucky i was a guy looking, not a woman as I'd agree with your friend that I found it easy.
But some nice ones are out there. I had a couple of nice relationships that didn't work out long term (once them, once me, both ended respectfully and honestly, no cheating etc), before my now long term one. So as I've seen said on here before, its probably just a numbers game. Go on lots of first coffee dates, but have boundaries and don't take any sh*t!
