Who cares if you cannot teach an old dog a new trick - you can teach a horse to tuck itself in. Well maybe you and I can't, but a woman in Australia did! Watch as Rumba the Wonder Horse tucks itself in for a cozy nap.
My sister was bucked off of a horse when we were kids. I was there when it happened and was pretty freaked out. She ended up with some bruises and a broken arm. After seeing this video, I think my sister was pretty lucky.
Everybody should try having sex in different places. It's a completely different experience doing it somewhere unusual or risky. But I don't know if I would recommend humping at the horse track while the ponies run by. But, hey maybe you should.
