@ Bogi_Khaosa: My knowledge is limited only to Catolic Church clergy - yes, they drink a lot, in fact many of them can outdrink a soldier, lawyer or actor and those are really heavy drinking proffesions (at least in Poland).
@Shadowkat: Weak willed? Certainy not, but You would think that a person (nevermind of what gender) that comes out of secluded monastery for the first time in her/his into a place that (compared to that monastery) is full of fleshy temptations will, at least, have a couple of restless nights?
As far as SMs and sex is concerned, Icame to conclusion (fluffwise) that genetic modification that transform them makes more alike their primarchs in certain aspects and that also mean they have some distance, genetical kinship with the Emperor himself.
I mean, look at the way chaos SM are tempted, even those that came to worshipping Slanesh were not persueaded by simple "Join me and You can !@#$# like crazy".They had to be tempted with something personal and intimate that couldbe turne into an excess.
Another thing: SM are, in a way, living a life not so different than millitant AS (train, pray, fight) and there is no SM Diologous or Hospitalliers that could tempted in a way I have described.In fact, situation described in second part of "Space Wolves" series (don't recall the title) shows a situation when a SM have a personal contact (starts seeing her as a person) with a woman and grows attracted to her - this situation makes perfect sence to me, only this something really rare.
P.S. If You are reffering to my remark from "derailling" part of discussion - I thought that was evidently tongue-in-cheek - my apologies if You took that seriously.

) most of the Horus Heresy novels I must say that I sensed some homoerotic overtones trroughout the saga. Although Space Marines seem unable to actually having sexual attractions (due to not only their training and mental conditionin but surgery and biochemical treatment to their brains as well), they are certainly not above romantic feelings for eachother.
