just wondering. i remember a conversation i had with a straight guy. he told me that when he see an erect penis, it turns him on. when he watches straight porn (guy and woman) that he cant help but look at the guys cock. i think its fascinating. be completely honest here. we're all adults here. if your not ashamed then leave a comment. does straight guys jerk off when seeing a penis? is it because of its size, its hard, soft, you were able to see it for a long time? do you check out guys penis on this site? if yes, why? if you are straight and have jerked off because of seeing a penis, what was it about the penis that made you jerk off?
