With all honesty, OP's hand actually looks feminine.
>>10133472 is wrong because men tend to have "blockier" hands, down to the bone, so if some twink/tranny were to starve himself to look feminine, the hands would still be a dead giveaway he's male. There are exceptions, I've seen cis women with "masculine" hands before, but it's a rule of thumb.
That being said, OP, don't make a point that you're female in your posts, or else horny autists like these fucks will argue about whether or not you're a tranny, not to mention that "Tits or GFTO" is an imperative practically as old as the site itself. Never expect a proper conversation when you express your femaleness.
