And if you really think about it, if a guy cannot "get it up" for a real woman, and can only find pleasure in his own hands, he's become homosexual.

Um, no. The guy is still sexually aroused by the images of naked women. He is imagining that he is being pleasured by the porn girls, not by a man's hand.

Following your logic, if a guy masturbates while also being able to have sex with women, he is bisexual.

He is imagining that he is being pleasured by the porn girls, not by a man's hand.

But he isn't being pleasured by the girls. It is a man's hand.
In any event - if he can only get aroused through imagery and not the real thing, then he's handicapped and impotent.
His love is in the sink.
I know you guys that are into porn don't like hearing this.
But face it - you're pervs.
And, don't knock the homos: You are closer to being one than you think.
