I have really enjoyed your site and wanted to offer some experiences that I have enjoyed over the years. When I was about 14 while riding one day bareback and I noticed that if I leaned forward just right, the rocking back and forth motions of the horse walking felt wonderful. For the first few times, I would move away when the sensations became strong not knowing what it was that I was feeling. One time I didn't move and I had an explosive orgasm. I was amazed anything could feel that good. I even told my mom about it and she just smiled and told me I had an orgasm which she explained was the height of sexual excitement. She told me to be private about it.
Over time, I have experimented with other techniques but still look forward to my horseback rides.
