Often, even on a picnic table in Yellowstone National Park!!!!!

All my dachshund pups were conceived in our back yard, there were three litters all up.
Unfortunately Max, my male dachshund cannot speak and tell me his opinion but I feel sure that apart from a few nips from the bitches he found the experience quite rewarding.

Hundreds of times in parks at nude beaches and even in my own back yard. Outdoor sex is really fine. Try it, you'll like it.
