i'm a 5"6 mexican and found out my current SO watches tiny asian porn as well, he's part asian and ik what you mean.

I knew another who only watched anime shit, another only watched black girls despite never having a black SO .Guys are weird, and their diccs just do. Also a lot of people fantasize about sex with their race, not racist just out of instinct. tbh i like latin porn more than white porn ¯\_(ツ)_/¯ my SO looks white af. i still like the sex with him. different strokes.

I wouldn't look much into it. If he was wanting you to act like an asian school-girl I would worry, lol, but he isn't and still enjoys the sex and he does not have an asian SO, he has you. Trust me, if he wanted to sex an asian gal you would not be with him. but you are, he wants you.

Jerking it is a time of peace lol, he's probaby not looking that deep into it.
