I like both, but I prefer straight porn more because I am not attracted to anal sex. I often start looking at gay porn, big dicked twinks giving head, jerking off etc, but often swap to straight porn since I prefer to see a big cock fucking a pussy, let alone my love for the female form.
The bi wave is real though. Sometimes nothing will beat watching a big dicked twink get his cock sucked till he cums in his giver's mouth. Like sometimes you crave gay dick and that is it. But the same is true with straight porn, too. Sometimes nothing is better than watching a hot couple make out passionately as they please each other until they both get their fill. Sometimes you fucking need pussy and there is no substitute.
