Its sadly been a long time but I've been with several. When I was younger and horny all the time I tried it with most farm animals. I did a lot sheep, a few goats and a couple mares. Once I learned I could have sex with a bitch though I pretty much stuck to them since it was easier and didn't require going out of the house at night. I must of had the two family bitches thousands of time over the years through my teens and early 20s. Once I left home though I wasn't in a position to have a dog and though I'd like to get one now the wife isn't entirely on board with it yet
