I dont wanna be some damn Football player so that I can fakely attract women, and from my experience most girls that act shy or cute are absolutely clueless about what to do in bed and simply lay there doing nothing, ---> Boring.
Yes you wound up likeing diapers... so what, be glad you didn't end up with likeing Poop, drinking blood or being tortured or some shit. I mean, We like in a Crazy and ultimately strange world. One doesn't have to look very far on the internet to find some REALLY weird stuff, people getting murdered, tortured, hacked to death with some machete in india... I mean, It simply proves that we humans, think very highly of ourselves and most time, for the wrong reasons.
It's a kink, everyone has a kink. I've been with a women in the past that liked being choked when we're in bed, hell i hear thats pretty comon too.
You know... you can still hit the gym, get pumped up, have a great physique right? Or you can still be anything you want in life, an actor, a programmer... likeing diaper doesn't take away the fact that you're you.
I was in the same boat as you are right now a few years back. I'm 25 now and learning to like that part of myself. Everyone is the same out there and they're all boring to me. Diapers only spices things up. I personally still enjoy normal sex.
Come back to reality, where people are actually living and not roleplaying their life. You can still be anything you want, diapers didn't took that away from you. You can get girls to fuck you by being a footballer sure, in Korea you can get the hottest chicks being a pro at Starcraft 2 (video game), But is this really what you want or you'd rather have a girl that likes the way you are, what you do. Who you are? that is willing to participate? the first is a 3 months relationship and the other is a magnificient friendship and alot of fun that will last much much longer ;)
recently took notice that my own mom, which is VERY normal mind you, keeps reading all those BDSM romantic novel all the time. With people having some weird sex all over the places... We all have our kinks.
