The Core Mechanics of the Guide to Unlawful Carnal Knowledge (www.netbook-of-uck.net) have, of course, been finalized long before now, so I don't propose rewriting it. Instead, I offer the following revised version for the consideration of anyone who basically likes the GUCK but wants to develop some house-rule variations to make it more viable for inclusion into your campaign. As I see it, the GUCK's current design is good for a specifically sex-themed campaign, but somewhat less useful for conventional games.
The primary problem I have with the original core mechanics is that they provide very little return on a character's investment of skill points and feats. In any campaign other than a specifically sex-themed one, few players would find it worthwhile to drop any points into the Prowess skill. A character needs either to master the skill or else forego it entirely, possibly in favor of magic spells and items that do the same job, or better.
One major problem is that the base DCs are unreasonably high when compared to the normative examples in the SRD. For example, the DC to raise a female character to Climaxed status is 20: a "challenging" task with the same difficulty as swimming in a stormy sea.
At a rate of one Prowess check per minute, a *normal* male human (Cha 10, no Prowess ranks) must rely on some lucky rolls to bring his wife to climax in under half an hour's time. With the current female DC progression of 16/18/20, he needs four minutes, on average, to arouse his wife, then about eight more minutes to bring her to Peaked status, and finally an average of twenty minutes to get her the rest of the way to Climaxed status. The man's own DC progression is 13/14/16, so his also-normal wife needs about ten minutes on average to return the favor.
On this model, a character needs several skill ranks -- which in D&D represent training and experience beyond the norm -- just to have a reasonable chance of success in a sexual encounter. This does not reflect the world we know, nor a reasonably constructed fantasy world either. Thus, I've reduced and flattened the table of DCs. The revised DCs still may not produce a real-world statistical success rate, but they lessen the bias against average characters.
I've made wholesale changes to other mechanics, such as the resolution of climaxes. If a "super-climax" status such as Ecstatic is really required, it should be a magical effect, not part of the normal Prowess mechanics that requires its own set of DC values. In this revision, a really good climax is simply one that lasts longer, with DCs increasing linearly for successive rounds spent in the Climaxed status.
Yet another change is the Recovery status. Formerly, it raised the DC to bring a male character to Aroused status by +8, thus: DC 13 + 8 = 21. DC 21 is difficult, but not too hard for a character with a total bonus to Prowess of +5 or better. She can get the man back in action in four or five minutes on average. I felt that this should be a more unusual occurrence, and changed Recovery to add DC +20, with that penalty reducing by 1 each minute. Perhaps a +15 penalty or even a bit less would be more reasonable; I'm open to debate on that possibility.
Techniques (formerly "proficiencies") are another big area of change, particularly with regard to Penetrative techniques. Again, the basic issue is return on investment: with perhaps 4 to 8 basic positions in the typical repertoire of a sexually active character, it seems silly to make the character buy that many Prowess ranks just to get good at what he normally does -- and even more ranks if he also wants to improve in other non-penetrative techniques. In the revised system, he can gain proficiency in 8 positions for only 2 ranks: each rank gets him a basic posture (reclining, sitting, standing) in which he can use four basic positions (frontal, rear, side, riding). There's some arbitrariness to that grouping, but it seems basically fair.
If it were reasonable and intuitive, I'd lump more techniques together in like manner, making it cost less to acquire proficiency in them. Why should we be this generous with technique proficiency? Well, because Prowess already has a more limited application than other skills. Stick a skill point into Spot, and you have a 5% greater chance to notice pretty much anything of importance. Stick a skill point into Prowess, and you have a 5% greater chance to arouse your target *using a particular technique*. It just isn't worth all that much in game terms. Which leads me to...
...Sex Tricks. I'm in favor of reinstating this basic concept from a much older version of the Guide. It's a good way to add personalization and flavor to a character, and it makes buying a rank in Prowess just a bit more attractive. These should largely replace the lesser varieties of Carnal Art feats, which are ridiculously underpowered except, again, in a sex-focused campaign. For your player who wants a spicy but still-viable character concept in a normal campaign, Sex Tricks are the way to go, IMO. Let characters have a proficiency *and* a Sex Trick per rank of Prowess, if it's plain that no one's interested in the skill otherwise.
There are many other small changes that amount to basic editing for clarity, consistent wording, and some occasional tweaking of the rules. (A character shouldn't walk around propositioning people just because he's Horny, for example. Some concept of "socially permissible outlet" should be implied, and now is.) I'm still considering the revision of some other elements of the Guide, to be posted at a later time, perhaps. Your comments are all welcome, of course.
