I ride Dressage. I'm not really into it too much...I just think it helps me and my horse become more overall -rounded...
I'm sorry, this topic has gone on for pages and I don't have the time to read through everyone's posts, but your mom thinks you are gay because you ride Dressage instead of doing those western events? That's horrible and very stereotypical!
Let me tell you that (english-riding) Equestrian sports are huge in Europe. Many of the top men-riders in the world compete in Show Jumping and Dressage and I have found the majority to be straight. I have a few trainers that came from Germany (one a Jumper, one a Dressage rider), both are men, both are straight, both are married and have a beautiful family, and on top of that are making tons of money working in the horse industry... On the other hand, I also have western-riding friends; one who is gay...
I am a girl and I ride pretty much all the disciplines but mostly do the Show Jumping (english) and Reined-Cow (western) events. Since "Western is more of a 'man's' sport" does that make me a lesbian? Since I ride both English and Western, does that make me Bi? Something doesn't seem to add up - I am [completely] straight.
There's nothing wrong with being gay, but stereotyping and assuming that this sport or this profession is only for one sex-preference is absolutely ridiculous.
(Your mom probably thinks that you must be gay because what kind of man would like to wear tight breeches? LOL...but still...that's just not right... :| )
I say if you like Dressage, just continue doing what you like! Good luck with everything.
