Honestly, with my mare, I didn't see a change in our bond with the addition of the sexual relationship. We already had a good bond, and the sexual part was just a bonus. When I really started paying attention to how SHE felt, that was when our bond exploded into what it is now. It's so much deeper and meaningful, and she shows her feelings to me in the subtle differences in how she acts around me. It always warms my heart when she allows me to hold her head in my arms, giving her the ability to easily pull away if she wants, but she stays because she chooses to. That kind of relationship is incredibly deep and caring.
