acutally, i agree with canon...a lot of girls can go through phases like that only kos their guys pisses them off...trust me, i was like that too...like " oooh...i hate my bf i might as well be a les...blah blah blah" you can fantasize bout doing things with gurls, experiment stuff with girls that bf/gf do...i've done that and i've kissed girls n stuff, but it's not something u just turn into kos guys can be assholes...i check out girls when im with my bf...and i actually do like this girl whom i've met and become really great friends with...
the thing is, experiment and see where your sexualiy takes you...anyhow, im bi!! :)
