@space girl 🪐 "@space girl 🪐 Oh, no you didn't say anything offensive, not at all.
It annoys me, that people belittle the impact OCD has and see it as a quirk and not what it really is - a debilitating mental illness, but that has nothing to do with your post.
POCD is a subtype of OCD. On this app I daily read at least on post of someone who suffers from POCD, so it's not that uncommon.
As you said, it is a theme, that's more taboo, than say Order/Symmetry, or Health Concerns.
Of course, I'm not a professional, nor do I know your sister, but I highly doubt, that an OCD sufferer would say "I'm so OCD, my picture has to be a certain way, or it annoys me." But I digress.
When I was younger, I only found one article in my mother tongue that was about POCD and in that article it said, that only men can suffer from that OCD subtype, which left me crushed, as I'm a woman. I felt so horrible, as I suffered from something, I wasn't supposed to suffer from. I felt so alone. Then unfortunately only many years later, I thought "Hey, I am fluent in English, why don't I check and see, if there is more information available on POCD in English."
So that's what I did and I found a lot of information regarding POCD, non of which contained anything about this subtype only effecting men. Moreover, everything I had felt was unique to me, like urges and groinal responses, was mentioned and I felt understood and, for the first time since POCD started, I didn't feel alone with this condition.
As I don't know, how much you know about this subtype, I'll share some links here, I think they are worth a read:

If you haven't talked to a therapist specialized in treating OCD with ERP, please consider doing that.
ERP does help. I went from leaving the sidewalk to avoid a child comming my way to spenind an afternoon with a friend and her daughter. My POCD still attacked me, but it was managable and I really enjoyed that afternoon, having BBQ and playing games together.
