Considering the contents of female oriented erotic smut and literature, I'd say most women probably fantasize about a very similar thing (the whole strong knight in shining armour thing). And in the end, as far as fetishes go, yours is actually pretty tame imo and pretty fucking hot, too… I might have just got infected.
Unless your girlfriend is a boomer that is only interested in missionary sex for the sole purpose of procreation, she probably wouldn't mind playing it out for you once you explain to her the fetish and why you like it. And if she does, well.. you can always do better than a judgmental bitch, right?
The best way to go about it I think is just to sit her down and tell her you want to do a bit of roleplay, hell, as a drama student she'll probably even be excited for that. And tell her you have a kink (pretty much everyone does) and then just level with her.
You're not a pervert for wanting to feel like a hero for your lady, anon. Quite the opposite I think.
