Why lie? What was the point? It's exactly the same as Jake Herbert...it was clearly a woman! If you won't do a video with a man or trans female and all you've got is a video with a biological female...then just post that. Yeah, it's not going to appeal to your market, but then you're making a song and dance of being straight anyway. There's always going to be someone willing to pay for a video they don't really want to see, just because they're gaga over you.
If you're going with a trans woman, FINE. Use it, milk it for all it's worth and enjoy the money you'll earn from it...but don't lie. Lying is the most off-putting thing and the fastest way to lose subscribers.
