Why can*t i get a girlfriend ?

I*m 18 years old and have the perfect male body, height, penis size, well i*m like Brad pit in a way, but still i can*t find a girlfriend. : ( I had a ****** up childhood and it left it*s Scars, when i was a kid girls used to tease me that i was ugly and nerdy. Well now i*m afraid to go ask girls out when i even wan*t to i frezze up and get the flashback of the past. my best female friend had sex with me yesterday when i told her what i*m telling you right now and said i was amazing and should not have problems with picking up chicks, so how do i solve my fears ???
