This seems reasonable.
Except #5:
1 - just because they are very aroused, doesn't mean they want to get pregnant.
(though, "Drunk with High Arousal, could negate what they "want, or care"

)
2 - Perhaps,
Vinfamy, could (or has already), created a
stat, that certain,
(a % chance), females want to get pregnant, or have a "want-to-have-babies" fetish

!?
3 - Fertility, hmmmm, kind-of-a-wildcard, here.
It shouldn't be a factor, as in, she wouldn't know how fertile she is.
( she just knows, (or doesn't

, low-intelligence), by her cycle, when she's most likely to get pregnant )
But, if as in my #2, it could be used as a factor,( as a "high-fertility" pushes her fetish's desire ?) for that
stat.
I'm currently still in version 3.5, so I've had no experience with what everyone is discussing.
But, since reading all these postings, I'll refrain from trying out this newest version.
Instead, I'll wait till the next version, that will have all the 'kink' & fetish (pregnancy), I'm interested in.
(hopefully, that won't be affected by this version's problem of " condoms-working-too-well" .

a.k.a. "working-not-as-desired" by many currently playing)
Still, this seems to be a good base, if nothing else, to work from.
