ZIPOk, my flameretardant suit is on.
If she wants sex, are you saying you won't give it to her? Is this because you are "bi" or because you don't like her "that way"?
She's Japanese, you don't really think she loves you, do you?
Don't you think she just wants a cheap place to stay?
You better tell her you are gay. If you tell her you are bi, and like to have sex with some women, but you don't want to have sex with her, that seems pretty mean.
Besides, she just wants free rent, and free food, and anything else free she can get out of you.
Being gay means you don't have to pay, right?
