CDs on this site are almost certainly at a much higher risk of needing to transition. The ideas "this is just a fetish" have been really discredited for TS women. Don't expect 'em to hold up to scientific scrutiny for y'all, either. Sorry.

I feel fairly certain there is a relationship biologically between a CD and a TS, and probably there are biological reasons many don't transition. We don't know what they are though, nor how to tell someone's fortune - are they just a CD or a TS?

It may be cold comfort, but no one can offer others assurance about any future outcome for anything. If you base your marriage on that, you set yourself up for disappointment.
