horse "relations"

something's been bothering me about people saying:
well I'm sure the retired horse will enjoy his new career at stud
many of you are probably kidding, I know
but just wanted to clarify, horses do not get any pleasure
from engaging in sexual intercourse
only two species experience pleasure from sex
and they are the human & the dolphin
(with the exception of those humans and/or dolphins
having sex with me )
