(NSFW) Gay guys, questions about your "alone time"?

I am straight, but I have a friend, who will remain unamed, who claims to not reference any material, gay or straight, when he masturbates.

I think my friend, is just sexually lazy in a way, and just goes with what’s easiest, which obviously is the gay community.

So, when you guys (gay guys) masturbate, do you fantasize about women, men, a combination, or no fantasy at all.
