Wow, this is like a Sliding Doors scenario. I'm 42 and had a very similar experience up to a point.

My friends were being social in high school and I stayed on the screen. Want to go to a party? No thanks! Want to go to a dance? Nah, got something going on. Want to go play basketball?

I did not stay home, I went to parties, met girls, did try my hand at making porn and it was pretty hot, but the women who participated were damaged goods, and it was also dreadfully sad to watch. Got a job, met my first gf, and I've been with her best friend for 23 years and I love her to pieces.

My hands also started going bad around 14-16, it wasn't immediate, but it would eventually lead to me being generally unable to play video games without paying a nasty cost for it. Now I only play top rated games I am really interested in, it's infrequent.

I have never preferred watching porn over being with a woman I cared about. Masturbating does not fill the role of lovemaking for me, it doesn't satisfy me. That helped, I'm sure, avoid the trap you fell into.

I also had issues with my weight. Still do, probably always will have to watch what I eat and regularly diet. I could lose 25lbs right now in fact. It all boils down to calories though, eat too many, you get fat. Eat less than your BMR and you lose weight. It's very predictable. It's not fun dieting, but it's simple, let me know if you want help losing that weight.

I live with a cat

My man! I am on my third cat, Gizmo. The first two lived long happy lives although I regret now some of the things I did. Gizmo gets the benefit of my experience.

They say the best time to plant a tree is 20 years ago, the second best time is now. Might want to try to change things before you die.
