Does anyone have any advice for her?

I'm not sure what kind of tips would be helpful tbh. Aside from obstacles from difficulty from other people, it's really just changing your gender identity. Acting how you genuinely are. There isn't much of an actual shift to make, since wanting to transition doesn't change your core personality. Just be prepared for other people to oppose it since people really like to get into other's business

Well, you're probably gonna have to stop calling her your boyfriend for one thing.

Its nice nice to see people are understanding rare today

If she hasn't already, suggest that she join a self-help group for people in transition.
This will help her find support among people who know the pathways, the difficulties and the benefits.

As in just for a while or permanently

I to would love it, apart from my wee willy winkie. I’d need to keep her to remind me I wasn’t a real girl.

I’m too old for this shit.
