I don't know how many people here have read the webcomic "Ménage à 3" by Gisèle Lagacé... but I just have to say it: Straight Girl reminds me a whole lot of Sonya.
Sonya's catchphrase "I'm not a lesbian!" that she likes to say all the time (especially when in bed with another woman, scissoring or doing cunnilingus) could totally be this girl's motto.
I love that webcomic.
Last news, Sonya has a new girlfriend: a James-Bond-like international spy who just left for Europe on a mission. Naturally, Sonya went with her.
She still claims that, why, of course, she's obviously not a lesbian. :P
