I didn’t consider it a “diss” (as such), but friendly banter. Had you but told me you actually wanted me to insult you, I’d gladly have complied.
If you’re as “comfortable” with your “own gender” as I suspect you are (your defensive homophobic remarks notwithstanding), one would expect you “to brush…off” any other member of the opposite sex, not just myself. Don’t worry: Your secret’s safe with me, gurlfriend!
