Hi Kris--I'm glad you like your lessons. Me and DH ride English--I'm an old "saddleseat" rider and DH rode "hunt seat". I had a five-gaited American Saddlebred mare (excellent trail horse); DH had a huge bay Saddlebred gelding he rode as a hunter. We rode together before our children came along.
I stopped riding in 1994 as we outlived our horses and started our family. Our girls are now 13 and 17, and we are both back in the saddle. There is a wonderful Saddlebred barn near our house--the trainer is the best caretaker in the world. She has a really neat niche of affordable lessons, affordable leasing, reasonable board. She makes riding attainable for us middle-class folks. She's trained and shown world champions but would rather have a barn full of truck drivers and nurses than work for rich folks. 
I started riding back in November. I take 1-2 lessons per month and lease a wonderful lesson horse. I really find that posting a trot English style really works my core muscles and is making me a stronger cyclist.
Keep up with the English riding lessons--your cycling self will thank you!
Fit and Fabulous on a Bike...Decrepit on a Horse!
