Reading your post sounded like I might have written it.

I attribute it to more than something in the blood, I think its a genetic defect, unique to many young girls and women, something in the DNA.
If I had known about this when I was a teenager with hormones, I might have hung around stables given the M/F ratio. But now I realise that would have been futile - boys have no hope of competing for attention against the horses.
Around my place with every new horse I move one more slot down the food chain in the family. I tell everyone when I die I want to come back as one of Mrs. GRG55's horses - they get treated better.
