I'm a guy.
I don't know why, but being a guy in a state dominated by female riders has done a lot of good for me.
First of all, its easier for me to talk to women.
All women like horses, so that doesn't hurt my chances... "would you like to meet my horse? We have a show next weekend, maybe you can ride him."
Some people said that being around women for most of my adolescence matured me faster, in the same way women generally mature faster. Of course, I wasn't without my guy friends. All of my best friends were guys that rode.
If someone wants to make fun of me, I either ignore it or tell them where to put it. It's given me a pretty thick skin, especially when I was younger. Middle schoolers can be brutal. Nowadays, people think it's more interesting than anything.
