Why do males watch lesbian porn movies?

Although I'm a male and I don't understand that.

Because they get turned on by watching two girls touching each other and making out. You know, I asked the same question to one of my guy friends and that was the answer he have me.

It is a form of voyeurism where the person watching gets a thrill from seeing something that is forbidden or at least, something they aren't supposed to see.

Inferiority complex. They love the way both girls accept each other. The males who like these movies don't feel accepted by females and lack sexual self esteem.
