LOL!! No, I wasn't goofing with you. Maybe my horses are weird, but it works for me, and if you actually scratch ON their butthole, they'll raise their tail almost straight up. Maybe mine just have itchy butts, I don't know. I tried anyways.
Well, even though Becky and I are sitting here talking about horse sex, I think yours was an even more awkward conversation to walk in on. ;~D
