easing her in

anyone know the proper amount of time
for each phase--of getting your girl to cuck you?

my girl now controls my orgasms already
i bought a harness and dildo (bigger than me)
and she gets to cum whenever she wants

and i get very submissive
but i brought up the cuck thing and she shys away and doesnt like the idea of another man in the picture *(althouh she likes the idea of going dancing ..and maybe dancing with another guy while i watch )

whats my next step ?

thanks!!!
