Well it certainly would be embarrassing for her parents to see it (assuming she's living with them). But, how many girls are gonna laugh at another girl for having a dildo? A few jokes here and there, but most younger women have them and aren't exactly ashamed. Hell, I had a friend once tell me about her dildo. I don't really know why but I asked her out a week later and she said no, so it wasn't like she was sending signals.
Now male sex toys will result in total humiliatian for guys, even though many men have them. My university school newspaper did an article about male sex toys once. They interviewed about 10 different sex shops, they all said they sell about the same amount of male sex toys as they do female sex toys.
