My favorites are amateur porn with female domination. But good amateur porn of any type is hard to find. There is another thread for ******* porn; I don't particularly believe in the effectiveness of ******* porn, but ones that give you the feeling that you are willingly submitting to having your brain altered and include actual transgender actors are a bigger turn on than clips from heterosexual porn pretending to be sissies or suggesting that you might become a sissy by watching interracial porn.
Here is a great 4 minute amateur cuckold video.
