It's all in your head, bro. I met a guy in NYC who claimed to have 100 lays (of course he could be lying but I suspect he was telling the truth) and he was the exact same height as you. I met another 5'5/5'6 guy in NYC who is extremely charismatic and he had no issue getting booty. Cajun is also another elite "PUA" who gets more booty than a toilet seat despite being 5'5 or 5'6.
I can find example after example after example.
