He's dead on about having to relearn with every woman you fuck. I HATE that shit, ya complicated fuckers.

The challenge is a lot of what makes it fun.

It's only a challenge if you actually give a shit. But when you do, it can become work.  

Not so difficult when it comes to fucking - only so many ways to skin a cat; locate the spot and lock on target.

But twat licking on the other hand...by the time you're putting the fifteenth technique in your repertoir into action, and your tongue feels like it's been slammed in a car door, and your jaw, through repetition, has accumulated more muscle mass than your fucking biceps, she's already decided you don't know what the fuck you're doing and is searching for a tactful excuse to remove herself from the situation and/or preparing for an oscar winning performance to convince you that you've accomplished something other than squaring up your jaw line.

Shit, even when you do figure out what works for her, you'll likely be able to bite through 1/2" rebar by the time your done - see first part of skit; trying to get her to focus. 68 and I'll owe ya one?

Now that was some funny shit.
