From what little I've heard men say about this taboo subject, most of them are like me and think it's somewhere between icky and repulsive.
Yea and out of these type of men usually exist a large amount of men who are actually intrigued at the thought of being anally penetrated,which in many cases leads to the confusion of being a Heterosexual or at most a Bisexual.The icky and repulsive hostile responses alot of times are indications of a coverup to how they truly feel due to social teaching that being penetrated equates to a loss of manhood.Many of these guys deny and have hostile responses toward it,yet engage in it behind closed doors or desire to.But you knew this.
