Is it normal for my girlfriend to be turned on by this?

Tell her next time you want to be the principal.

As far as you know, it's just harmless fun. Don't accuse her of anything until you have evidence.
Sounds hot anyway.

IMO, you're worrying too much. Do people who play Grand Theft Auto go out and kill prostitutes at gunpoint? Very rarely if at all. it's all harmless fun and it will heat up your sex life. You're a lucky guy to have a GF into hot role playing. It's normal for her to be turned on by
something with personal relevance. If you were a teacher around horny, attractive adolescents in the prime of their lives, it would abnormal if you weren't turned on by at least one of them.

I'm a human sexuality educator.

Yes, it's normal. Reason being- 1) She doesn't consciously control what arouses her. 2) We don't know when this fantasy became arousing to her. 3) We don't know, and never will know *why* she is aroused by seeing you dress as a school boy.

I could write novels of guesses. Perhaps she only recently started discovering this type of role-play and enjoys it because she gets to be the one in "control" and sees herself as more dominant. A teacher has "power" of the students. I know as an educator it's my responsibility to "control" the room of students I teach. She likes to fantasize about being your teacher. That doesn't mean she wants to have sex with students. A typical person can decipher the difference between fantasy and reality. This is just a fantasy. Or just think of this way- what if we analyzed every other kinky type of role play the way you're viewing her fantasy. Some people enjoy being spanked by their "daddy". But we understand that it's not real. They don't really want to give their father a call and ask them to spank them for arousal. That would be weird... lol. But my point is, perhaps she likes the "control" of the role-play.

Maybe she had this fantasy long before she was a teacher. It just so happens that she wanted to be a teacher in her reality. Assuming she's not secretly a serial killer, she's most likely got her head on straight. But you two definitely need to talk more about it. You, as her partner, need to be open-minded to listening and trying it. But if you're still not comfortable doing it, you have to be honest with her and tell her you just can't do that for her. Which, personally, I'd find a little upsetting. I mean, you have to understand, as a human sexuality educator, I've heard of a thousand kinkier things. Some that actually *are* quite dangerous. This is just a costume and some role-play. If you let go of this thought that she's up to something else as a teacher, you might really start to find the erotic fun in what she's suggesting. I'm not attracted to women, but I personally think it sounds kind of hot, to be honest. Anyways, definitely talk to her if she still wants to try it.

I would say let it slide. If you are the same age and she is not molesting kiddys why does it matter? If you are not comfortable with her pervy fantasy tell her that. This is also a pervy fantasy that seems to be very popular among people. However I find the thought of sex with a teacher creepy. I do not understand how children want this. I never understood the concept myself.

You're lucky

My Girlfriend makes me dress up as "Paper-bag man"

I think this is completely normal and maybe it is just a conincidence that she is working at a school, maybe she has had this preference in the bedroom for a while

She likes stuffing soggy weetbix up her ass and farting it onto your face.

Probably not very appropriate but with what people are into these days just be thankful it isn't anything too disgusting and extreme like excrement or something. It's not like she's doing a student, she's only asking you to wear uniform.

It is called role-play for a reason. Wouldn't you rather she do it with you then do it with a student?

holy red flags, batman!

I don't see the problem. If dressing up does it for her, then why not play along?

Itcould be worse she could lke items from fifty shades of grey. That may be a bit freaky.

I don't see any problem with it. Plenty of guys like girls in schoolgirl uniforms.

Over 9000 people have fantasies that we think might be weird.

Mine is wanting to have sex with chunli but my wife wont wear the costume.

Tell her you're going to diving school and wear a scuba suit to bed.

As long as she doesnt act on these fantasies in real life it shouldnt be something to worry about...then again it is disturbing...I can see why you are concerned. Perhaps some relationship counselling/sex therapy would be helpful in this case.

She may think it's harmless fun, and she could be thinking nothing more that that I think it's strange seeing as how high school kids are 14-18. Some haven't even hit puberty yet

I could tell from the first paragraph you're gay. But think about it: how did your girlfriend get the boys school uniform? ...... Yep.
