Understand its not your fault and you shouldnt blame the world. Everyone goes through this at some point (esp guys) - be it skinny, fat, coloured or not, tall or short. Everyone has their preferences.

Giving up on actively finding a girlfriend is probably the best thing to do in your situation - but not out of spite - some women find an attractiveness in someone who has fun in their own presence. People want to be a part of that joy. Being bitter will only drive away friends and potential relationships.

With that said, do your own thing. If being skinny bothers you (and you alone, not what anyone else thinks), hit the gym and eat more? Try more activites either solo or with friends. Maybe even some extreme sports which a partner would otherwise not join you in. Just enjoy life and someone will come. I know people who found relationships in the most unexpected of times and places.

I understand theres an inch in the intimate department that cant be scratched with just normal friendships but idk, resist tbe urge or find other outputs to bring your urges back down enough so you can just be you and comfortable
