"Going to have sex with two ladies at the same time? You need a strong erection, or they will have to satisfy each other. You really need Viagra!"
There are just so many things wrong with this. First of all, the author is wrongfully asserting that "two ladies" sexually satisifying each other is somehow lesser than if a man did it. Compare the number of married woman who have never or rarely have orgasms with their husbands to the numbers of women in long-term relationships with other women who have the same problem and get back to me, ok?
Second of all, That statement assumes that a nice stiff one is the only route to sexual gratification, which it isn't. However, if a stiff one is what you're after, viagra is not necessary.
I'll refer you to Bitch and Animal's song "Best Cock on the Block" from their album, Eternally Hard.
If you still don't get it, try the spoken word piece "Cute for a girl" by Alix Olson.
