Look fellahs, I'm no skin doc and I don't even play one on TV, but I gotta say that I'm not about to let a chick with a rash start yanking the skin on my sensitive parts -- and I don't care how huge her tits are or how gorgeous her ass is.
Sure, she'll tell you it isn't contagious -- I'm assuming her other employment opportunities aren't half as lucrative as that of Pud-Puller. Meanwhile, I'm the one who has to try explaining to my better half that the mysterious blotches on my knob are really just an allergic reaction to the new soap they have down at the gym.
I'll be the first to admit that my standards peak somewhere down in the basement, but I have four general guidelines to life that have served me well:
1) Don't get drunk on sloe gin
2) Never admit to love
3) Don't sign anything
4) Run like hell from sex workers sporting open sores, rashes or any other leaky pustules.
P.S. Besides, nothing sounds fishier than a "she swears it's not contagious" testimonial from a first-time poster.
