No reason. I'm definitely noticing an uptick in erotic quality. Aren't you? Some vids are still a little lame, but I overall...wow. Most of this is as authentic as a porn vid can get. I checked and they've actually done a few surveys and at present at least 70% of the actresses now are legit bi or lesbian. Didn't surprise me in the least.
May this inspire the uninitiated women watching, and listening to the sighs and moans of pleasure, to deepen in this way the close-knit bonds they already cherish with the women in their lives. Lesbian lust is only truly realized when friendships and familial and other woman-to-woman ties are thus nurtured.
