Well, I have been propositioned by a Jersey cow, some sheep and several dogs. I think they were propositioning me. I could tell by the look in their eyes.
I was once accosted by a large tomcat. He had been confined in a cattery for a fortnight which was full of the opposite gender - unavailable by way of the wire meshes. When he got home his hormones were flowing wildly and so my left leg was severely propositioned, with the claws of all four paws providing the purchase for the yowling furryfrotbag!
It was no easy matter to remove the amorous beast, let me tell you. At least the Jersey cow merely gave me a come-on look. Those eyelashes!
I've been propositioned by a Jersey cow more than once, some of them are crazy when on heat. In my case it wasn't the eyelashes, but the way she reared up behind me and tried to get a leg over one shoulder. Once she succeeded, pushed me through a wire fence* and spent the next five minutes being shouted at and chased around the field.
*The fence broke, not me, which made the chasing easier.
