If you don't want to take up Zaer's offer, I could referee a stand-alone for only two people. Be warned, though, that at times I have to go slowly, and most days will only get in one to three posts in any given game; weekends are variable, and I can sometimes spend a whole day at the computer, and sometimes have nearly no time at all.
I'd suggest the Brains and Brawn pair, but limited to Players' Handbook races, please? I'll be working almost entirely from the three basic books; I also happen to own Complete Arcane. And don't make the Brawny one too dim -- you won't always be together, and each of you will need to be thinking on your own from time to time. More plot than combat, rp-heavy. The proportion of sex would be mostly up to the characters; there will be plenty of randy NPCs (though not all of them).
I have a basic idea in mind, in a homebrew setting, neither too eccentric nor too predictable (I hope), and can take the game through a starting phase, after which we can all discuss continuing further. Characters can play any of the standard PHB classes, starting at second level, with twice the maximum amount of starting gold for the class, one Potion of Cure Light Wounds each, and one minor magical item, variable depending on class(es) chosen. Use the point buy system for characteristics; you have 30 points to distribute, a fairly generous amount.
If you're both interested, please let me know. And I like reading good background submissions.
