I regret wasting my life

I'll be turning 28 end of April and I'm still a virgin. Never had a girlfriend or even kissed a girl yet due to being mostly insecure. I feel like I wasted my life. I never really went out at all and instead stayed in to play video games and now I realize I regret it. I finally started going out recently and putting myself out there at clubs and bars and I notice I'm getting smiles or even catching girls staring at me. I even got called ''cute''. This is a revelation for me. This whole time, I thought maybe I was ugly, too short and unattractive, but I'm starting to see otherwise. I do have a babyface that still makes me look 19. I wanna have a ''hoe phase'' for a bit and sleep around since I never got to do that. I don't care if that makes me sound immature. I deserve to have the fun I missed out on because I was too insecure. Maybe it's not too late for me and I was just in my own head too much...
