Hi folks, here's another person de-lurking to (hopefully) contribute to the effort. I downloaded the currently available versions of the Guide a little over a month ago and spent some time tweaking things, trying out rules variations, running through encounter scenarios, and mulling over what seemed right and what didn't.
At first I set about expanding the catalog of Sex Tricks, which IMO are one of the highlights of the system: they permit a high level of personalization and lots of variety among characters. However, I soon identified two problems:
* the Tricks catalog was disorganized and tilted heavily in favor of certain ability scores over others
* few Tricks, if any, were available to persons of average ability
So, I started over with a different approach. In my new system, Tricks are handled in a manner similar to the acquisition of spells. A spellcaster has two requisites to learn/cast a spell: she must be of a sufficient class level, and her relevant ability score must be at least 10 + spell level.
Likewise, each Trick in my system has a "level"; this number forms the basis of two requirements. The Trick level is both the number of ranks in SP and the number of points above 10 in the relevant ability score required to learn the Trick. This yields the happy result of providing low-level, simple Tricks to persons with modest ability scores of 11 (or 13!), and it organizes the Tricks into lists categorized by ability score (similar to Psionics).
Here's the list of Tricks I've produced so far. Some are directly from the Guide, some have familiar names but are changed in substance, and some are original.

* * * * *
As you can see, there are no Tricks requiring SP ranks greater than 5 or ability scores greater than 15, which seems fair to me. Many PCs and NPCs will have a couple of ranks in SP; few are likely to have 10 ranks or more.
Also, basic Tricks such as Powerful Lvr, Dexterous Lvr, etc. are not only not required for other Tricks; they are gone altogether. It occurred to me that realistically, CHA is the primary determinant of sexual success. A strong or dexterous character may learn Tricks to get extra mileage out of his abilities, but he can't just substutute DEX for CHA, especially if he suffers a natural CHA penalty.
I have other homebrewed changes to the Guide, but these are the most substantial. Just thought I'd toss 'em out there and see whether or not they have any merit as 3E-ish rules.
