For all those guys who post that they are 100% straight, you might be interested in this. Experiments have been done with penile plethysmography (mercury-filled condoms that measures even the smallest increases in blood flow to the penis). Images of men and women were flashed to the study participants. The straight men who claimed to be only straight, and to only have interest in women showed MORE reaction to the male images than the straight men who were less definitive. In addition, as per the cliché, the more homophobic the straight man, the more increase in blood flow to his penis with the male images. So, at least for those in the know, know your penis! And be careful what you say, in case we've read this study!
