I'm 27 personally, and haven't been in any sort of romantic relationship or even kissed on the lips.
Now I'm at the point where I wanna wait til' I have my own place before I make any serious attempt at it, cuz I don't want to be judged for still living at home (Don't have a high enough income to move out).
I feel like once I seriously try though, I'll find someone eventually. I at least have that much confidence and self-esteem to know that I'm not unfuckable or anything like that.
I feel for you comrade, I was 21 when I met my first girlfriend and have only been in one other relationship and she turned out to be kind of a chud. I've had one drunken one night stand and it just felt hollow. You'll find someone, confidence is key and I'm rooting for you. My problem is the self-esteem part. Don't worry too much about not having your own place, if you meet someone that connects with you they probably won't care if you live at home you can always hang out at their place. Most of us struggle to afford rent so I think most people won't judge you for living at home especially now.
