Why is the gay porn i am seeing now different from last year?

AN EVOLUTION) HOW MY CONSUMPTION OF GAY PORN HAS CHANGED FROM ME AT AGE 21,
25,
30, and at age
35?

1. when i first came out,
   I exposed myself to gay porn showing non-anal-fun scenes.
   very confused when first time… & I cannot choose btw see ang moh men or asians…
2. AT AGE 25,
   now my tastes has changed,
   not yet tried anal sex so better learn… so start seeing those sort of videos.
   this time also smarter… no more big dick ang moh so…
