Actually, no. C-PTSD does not change your sexual preferences that way.
You don't have PTSD or C-PTSD. You're just autistic, which often comes with weird phobias to justify self-soothing behaviour.
Like a phobia for getting women pregnant is a mental justification for your emotionally autistic mind to your fetish for maternal figures. You feel safe with old women who won't ask you to be a man, but with whom you can be as much as a child as you want to be.
First of all, 45 (the age in which where I'm no longer afraid to insert myself into a woman) isn't old enough to be my mom. A mere 12 years; that's more in older cousin/older sister territory.
Second of all, having a phobia of pregnancy is one thing. But going as far as focusing on post-prime broads to circumvent a pregnancy phobia, that's on an entirely new level. Many men couldn't bring themselves to focus on post-prime broads, no matter how much the man fears pregnancy. Hell, even on this very forum, I hear there used to be an active fellow autist who shared my crippling pregnancy phobia...yet even he (from what I've heard) preferred young broads.
There has to be another factor at play for why I feel no romantic feelings at all toward young broads. Young broads can be nice to look at; no doubt (And I'd love to kiss/fondle a young broad, as well as watch a young broad pee). But the desire to get romantically involved (or have sex) with a young broad? That desire is simply lacking in me.
There's got to be another explanation (besides my pregnancy phobia/ASD) at play to explain my total lack of romantic interest in young broads.
And I already covered why the mommy issues explanation isn't it. Mommy issues wouldn't explain why my preferred minimum age of 45 remains unchanged, even as the age gap between myself and a 45 year old broad narrows.
