You're confusing biological facts with the views you have adopted as a result of being involved with the straight porn industry. Biological facts say that male bisexuality is common - in fact, Alfred Kinsey found that more than 50% of men have had same-sex feelings at some stage in their lives. I would rather go by what Kinsey says than by what you say.
As for women wanting to watch female-female action over male-male action, where did you get this from? I have no firm figures myself but, if you go by the number of women who watched Brokeback Mountain just for the kissing scenes, I'd say there's a lot of women who like to watch hot guy-on-guy action.
If you want to have credibility, take my advice: stop pulling assertions out of your ass.
