{A/n~ so basically the magical fairy said poof, now your boyfriend is a girl. And after the inital shock of it all. Just stuff you would do with them/ how you would act around them now that they are a female. I still said he because I am lazy as a mother fucker.}

Stan: 

You'd treat him like a princess. Like you'd paint his nails, do his makeup, do his hair. You would be having fun. Like bro he'd be so pissy and hated being a girl, but lowkey liked you touching him n' shii

Kyle:

You'd love to play with his hair. He'd get insecure about his cup c size. You wouldn't care, but like yea. You'd treat him the same aside that you would style his hair like everyday.

Eric:

yo, like there would be hardly anything different. Like he would be a total drama queen, but that's not any different than boy Cartman. He'd be the one to paint nails, do hair etc.

Kenny:

Kenny wouldn't even be different. He'd still be a thirsty little thot who want to fuck you. Nothing will change. Sorry

Craig:

He'd always be pissy. You'd practically have to beg him to get him to agree for you to treat him like a girl. Like he would still be hella overprotective, and he'd still beat up any boy, the only plus would be that he gets to beat up girls too.

Tweek:

He'd be all spazy, like more than usual. He wouldn't be able to comprehend why he was now a female. He'd let you braid his hair every once in a while.

Token:

He'd be upset. He wouldn't like being a girl. He'd hardly let you do any girly things to him.  He would still try to be a guy( if that makes sense :\)

Clyde:

He'd be super upset. He'd probably cry. he cry about how essentially he would be the bottom. You be laughing your ass off.  You'd do his hair, and paint his nails, but NO makeup

Jimmy:

I don't even know, he'd for the most part be his regular self. The only difference is that he will not let you touch him under any circumstances

Butters:

He would think being a girl was cool. You guys would be having so much fun. Like the stuff you would do would be so fucking lit, I literally can't even describe the fun shit you would do.
