Not odd at all. I've always gotten my horses to have a nice, slow, trot and it's so easy to sit it. It's why I prefer western, I like the casual relaxed feel. I did English for a few years when I was really young and learned to post and I know you can post western too.
My horses trot is really, really difficult to sit and it takes a lot of energy to do so. On another horse I ride, posting would be equally as difficult because she doesn't trot...she floats. Posted via Mobile Device
I love sitting the trot, I find it easier to apply leg aids at the correct moment and I also enjoy feeling the power of a nice big trot with a lot of spring and reach. Once I learned how to do it properly I almost couldn't stop doing it, I have to force myself to post (for warm-ups and on unfit horses - and even then I prefer doing 2pt unless my knees are particularly arthritic that day).
