Don't even worry dude, 5'5" is short but it's a good height. One of my cis male friends is 5'5", and a lot of the coolest rock stars are about that tall too. I'm 5'0" unfortunately and I always envy people who are even two inches taller than me. But I see plenty of guys my size and they look fine. The most inspiring one I saw was a very small, skinny dude that sort of resembled how I think I'd look in thirty years, and he was an awesome dapper gentleman. :p
Height doesn't matter. Confidence does.
