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.
Additionally your first time being with an escort shouldnt be ignored or shunned. That being said mileage will vary and may very well not be great let alone magical, but how many can say their first time truly was magical. I didnt lose mine until just a weeks before my 21 when I decided to hire an escort. Shit was fun, I let her know in advance obviously and booked an hour session (if i recall she even let the time lapse about 10 mins after but mileage will vary of course), she was easy to talk to, welcoming and helpful with everything. I did see her once more but this time for 30mins and again it was fun. That being said I didnt feel like it was something that I'd sorely miss. As such it wasn't another 2 years until I had sex again this time with an actual girlfriend. Now obviously as it turns out its even more amazing when you're with the person and have a connection.
