And now, I present to you...
Why one would logically think certain shemale porn might be more appealing than regular porn to heterosexual men.
I was thinking about porn the other day, and I got an idea. Why don't heterosexual men like some shemale porn? Please note that by 'shemale' I mean a man who is entirely a woman (boobies, face, voice, etc.), except he still has a penis. I don't mean all shemale porn. Shemale porn that includes a shemale and a regular male would obviously not be enticing to heterosexual men. But what if you had a shemale and a regular female? At first thought, you might think there is something "gay" about shemale porn. But if there anything gay about watching porn with a man and woman? I don't think so. Shemale porn is basically the exact same thing as a regular man and woman, except the man looks like a woman too. So it's almost like lesbian porn with penetration, sans a strap-on. How can that be worse?
If this is confusing you, perhaps some charts will help:

If you are a heterosexual man, I've no doubt convinced you to use shemale porn. Here's something to get you on your way (my gift to you): http://www.google.com/search?hl=en&q=shemale+porn
