Hey guys

firstly, thanks for clicking on this post. Sorry theres abit to read, if you can get through it though youre a legend. Truly.
So basically, im self conscious due to the fact that i look 15 years old, when im actually 18. There are no advantages to this at all - no girl in a club wants to close with a guy who they think is a 15 year old minor with a fake ID.
Just now, the girl i was really interested in has fallen into a relationship - literally the minute i was about to ask her out. I finally built up the courage to.
Id love to say "Shes just one out of many", but ive had so much failure, and dont think i have the potential to find a girl in a club because I cant be taken seriously for looking so young.
My track record has been SO bad, i dont know how i can possibly recover. Around 5 girls in a row have rejected me, and ive never had a girlfriend.
The thing is, girls find me hilarious. And "cute", which i think is the biggest problem.
I dont act overly nice - im aware of coming across as needy and desperate, so i try to hide this as much as possible.
Its as if girls just fail to see me as "fuckable". For example, a girl who said im the funniest guy in the world told me "I love your company - you dont intimidate me like other guys. Youre like a little brother to me"
Biggest shot through the heart. Seriously, the only opportunities i seem to have are with gay guys...what the fuck.
The amazing thing is, heaps of friends assume im a ladies man and ask me for advice. Truth is, im terrible with women. Not with shyness, not with opening groups, but with actually being perceived as attractive.
So. I need advice with what i can possibly do to recover. Am i supposed to aim for girls in elementary school? A girl in a club told me i look 12 last night...
lowest point in my life by far lmao.
Also, what are some general tips which can help me? ANYTHING is appreciated so immensely, you have no idea.
Thankyou so much
