You *know* you're a sad, lonely dork when you're first thought is:
Eyes of Sauron.... Tie-dyed. On acid.

Those just made me incredibly nauseous... Especially the bloody one and ones with 'hair'.   

The period cupcake.. eww.

So are these for bachelor parties, the same way they make penis-shaped cakes and chocolates and things for bachelorette parties?

I do not know. I do know that I often see them at productions of The Vagina Monologues.

I dunno, it's not really something I would be horribly excited about...   

For the record, the first winter Kyle and I were together, we gave our roomie (anybody remember Jooki?) a chocolate vulva on a stick.  We probably gave them to a bunch of our other friends, too.

Mmm, chocolate vulva on a stick.  We had them in white, milk, and dark chocolate, and they were yummy.

So edible penises are for women to enjoy when about to enter committed monogamy*, and edible vaginas are for women to enjoy when celebrating female empowerment and deriding female oppression.

...

When do men get to enjoy edible sexy body parts?

We get to eat chocolate in whatever other form we like, whenever we please, without freaking out about it and how it will affect our weight. Yet more evidence of our intrinsic superiority.
