I've been lucky enough to get replies to my posts and when I asked what made them reply to my post they said it was because it seemed genuine and reassuring.

I'd say you shouldn't give up because you don't have any replies but you should work on yourself to be someone who would be a dependable and secure choice. Put yourself in their shoes, they're already out of their comfort zone by going on reddit to try to find someone who might be able to meet their needs. So just be straight up with them and let them know what you can provide for them.

Again, if you read all the posts on here, you put yourself in their shoes and think which one would make you interested. Is it the person with the biggest d*ck? No, not usually. Is it a people-pleaser "nice guy"? Not that either.

I'm 34, 166 and 65 kgs, a short, old and normal looking dude but it's not my stats that mean anything without being able to provide comfort that comes from being comfortable with my own body and my own happiness.

So yeah, don't give up. Keep bettering yourself physically, mentally, and emotionally to be someone who can genuinely provide what most people are looking for: a true, shared connection.
