Hey how so 'Resist Self' is not a serious spell.
I like idea of splitting guide thus, because it's logical. However, I woudn't call hentai part web enchantment then, rather part 2 with 'hentai'-type name for it.
I like the silly stuff too. Yeh, it makes me think 'this is sooo tastelessly silly' but makes me laugh too. In world of where magic exist some wizards and clerics of deities of love (carnal love) might come with pretty weird inventions. Sexuality has many twists in real world, some of them, truly weird. Isewa, are you speaking 'unusual sex' in general should be in hentai book or just 'silly'?
Some realism is good, but hentai for example has another kind of 'reality' for it's realism. Regular porn works under its own realistic rules as well, though they don't go that far from reality.
Besides some items sold in real life to be used to 'enchant sex life' are pretty silly, sort of at least. Names, if nothing else. Those type of people who buy 'Real Dolls' in real life (and can afford it), would probably be people in fantasy world who buy expensive golems meant for same purpose, but more fun?/livable. Creations of magic tend to be more miraclous, than lacking technology or real world. Imagination is not enough I think, to guess the actual amount of stuff people would do and invent, if magic such in D&D existed.
Well anyway. Moving certain parts into other book would help make book more logical and useful. There are spells now in book I know, written very different theme in mind, for example. Separating these themes would not be such a bad idea. They would still be one book. Part 'one' for more common ideas for sex and part 'two' for extra themes.
Many games have common theme and leave additional themes for additional book. Yep, to sell more books too.
For example, Spycraft took out psionics/'chemical monsters'/mysticism and publishes them in separate Shadow..(forget what) Archer. Apperantly because many had commented, that they don't want to mix supernatural themes in their spy-games.
Though I don't know, if that helps book's reputation or anything like that. Some people just hate the subject of sexually concentrated themes in rpg no matter what. They are ok with erotic or mayhaps even kinky picture in regular product, but book including name 'sex' or 'carnal' makes their 'no' reactions kick in.
Oh, and our guide probably gets compared to games like 'f.a.t.a.l'
by people just go for them 'sex' as 'evil' or 'immature sexually frustfrated teenager "roleplaying"'. Ah, and on sidenote, I dislike fatal being mentioned in same sentance than our guide.
I've actully read some of it. System is for table/detail fanatic. Tables are many, are truly work of 'love' (for tables, and tables and tables). It is way too long. It is booring. It is not very kinky game, actually, because it's so detailed it is boring and because of it's theme. It's tone is negative and nihilistic. It has medievil (spiritual) world view right out of 'Malleus Maleficarum' ("Hammer of the Witches"). Many monsters were inspired IMO by said book at least, likevise many things concidering females, they omitted certain harm factor for males (from monsters, spells, etc), curiously. Game is neither very RL nor D&D in spirit. I suspect it became legendary though some flame war, otherwise it's name would not have gotten such attention. Very misogynistic depressive idea for a game. Few nice ideas for spells/critters, but nothing truly original. I don't recomend you checking it out, it's not worth it.
Nothing like our guide, that is.
Most use of for our guide will come out of 'amusement factor'. People will download it and laught at 'silliness' that some people actually wrote 'D&D guide to sex' and 'isn't that joke getting old' and then they might even read it and laught at some silliness they actually find in it.
Different people's ideas of silliness vary too.
Some parts might be used in regular games, by those people who are not bothered about book's 'name'.
Fewer would be those, who actually used the system for sex.
We will receive very little response from people, and people would commonly be very shy to admit, that some of our ideas/spells are cool and say using them.
That's my guess, at least.
I have a feeling, if make poll mentioned. Responses would come mostly from us.
