Thats crazy. I'm 5'9 and have had sex with hundreds of chicks.
If you are worried about your height, the worrying might be doing more to hurt you than the actual height. I knew a chick who was aalways worried about her nose. Nothing was wrong with it but she walked around like she was ugly cause she was mad concerned about it, and she radiated insecurity.
Then she would blame stuff on how her nose looked when really it was the vibe she was putting out that was screwing her up. Nobody cared about her fukking nose but her.
