Hey man, I had some of the same anxieties about being a late bloomer, never finding a girl, not knowing what to do if someone showed interest etc. This will probably not be new advice to you, but here we go:

No matter how old you are, it‘s never too late to start things. Go out and have some fun, socialize with women, try dating, do hobbies with women involved etc. Invest in yourself, have a basic level of hygiene and dress socially acceptable. At some point you will find someone who is into you, and if you are open and up front about your lack of experience, they will probably overlook most of the early dating blunders.

Just don’t go into it all with the expectation that something has to happen, or that if you do the right things someone has to be into you. It’s ok to fail, it’s ok to be awkward, you learn a lot from it.

If you wanna talk privately about this stuff, shoot me a dm.
