Since my tawdry past took place in the snoozy sphere of heterosexuality, I decided to consult Babette, my expert in all things Sapphic. See, that's the crux. If this woman is OK with being your little secret, that's fine. Then you might want to inform him. What he doesn't know. . . .
Sexuality is a fairly fluid thing.
I'd venture to guess that most people find themselves attracted to different genders at different times. Speaking of insanity . . . Dear Dategirl, My boyfriend proposed to me last week. I've been having doubts about our relationship, so I told him I would think about it. I was furious and haven't spoken to him since.
