She's asian and pretty inexperienced sexually.  I've spent most of my sex-active life exploring all sorts of stuff - fetishes, munches, toys, positions, etc.  We went to a sex shop together - she was pretty comfortable with it and we had a great time looking over stuff and talking about what the toys are for, etc.  Lots of giggling and fun. 

Then we got to the lingerie section and she suggested having a pajama party with friends to break in our new apartment.  I was really surprised and delighted that she would suggest this.  So I asked her if she'd ever be ok with having sex in front of other people, just out of curiosity.  She then got kind of quiet and closed off, and when we talked about it she got tears in her eyes from the thought that I'd be interested in having people watch us have sex.  

I'm having a little trouble understanding why she feels that way (I didn't want to poke and prod at the situation because we JUST got over a pretty low low in our emotional roller-coaster) - so I'm looking for input from anyone else that might be able to shed some light on this response.
<bot>: Girlfriend is comfortable in the sex shop until I ask if she's into exhibitionism.  She got very upset that I would even consider it.  Trying to understand why.
