Of course, part of the humor here is that some contemporary
condemnations of (male) masturbation -- particularly from the
religious right -- claim that it is indeed either itself a form of
homosexuality or else that it is a "gateway drug" leading to homosexuality.

Many years ago, a straight acquaintance of mine said to me.
"You know, I **love** my cock. When I'm enjoying my own penis,
I can **almost** get what it is that gay guys like about having
sex with other guys. (I didn't try to explain to him that being gay
usually involves more than just a fascination with another guy's dick,
that it's more often an attraction to a whole person, including an
element of emotional attachment, or even romantic love.)
