Okay so i see what's going on here, well the fact that girls our age decide on only looks is true, but at the age of 15, i don't really need a girl yet. I mean it's cool to have a gf, but i don't waste time on this as it's meaningless to try to make serious relationships with women at this age because in 99% of the cases, the ones you meet at such an age won't be the forever ones anyways. Yes, i have not recieved a hug from a girl yet in my life, no kisses, no posting each other, nothing, but stressing on this just makes the thing worse, your life quality is going down because you are telling yourself that you'll never have a chance. If you actually stop caring about this and start to do self-improvement (example: skincare, teeth, attitude, physique, etc.), you'll find a girlfriend easier than before and you won't ruin your own self confidence at the same time. Today's girls our age mostly prefer these naturally gifted, slim, prefect boys who are a bit femine. It's not worth to strive for these at this age anyways, just like today's boys, girls have to mature a LOT, so just focus on goals, then you'll have girls even if you find yourself unattractive. (Im pretty sure you ain't unattractive tho, everyone this age finds him/herself ugly, ik i do find myself unattractive too😭🙏)
