I may have posted this before but my fantasy (something that's impossible) is to swap bodies with my wife for a week or two. Some sort of device where we both get in, someone pulls a lever and we emerge in each other's bodies. Like a time machine but with different results.
This would allow me to have the experience of being a true female but in a safe way as I would have my husband (my wife in my body) around to experience being female with. No going to bars and picking up strange men, etc.
Of course, I might not want to switch back. Or she might not want to switch back.
Your fantasy? .................
