The minor problem is that I and plenty of other men who identify as straight dont see this as common behavior amongst other men only sexually interested in women. The major problem comes from women interested in men whom, completely within their right to do so, arent keen on desiring a man they've known to engage in homoerotic behaviors.
Is it really people's fun being messed up, or men wanting to enjoy something without being subject to the consequences of it?
Now for the record I do think societally woman should have a much more open attitude about it, which in turn would motivate more men to be forthcoming about it, but that doesnt mean I dont think there is a marked difference in sexuality between men whom exclusively seek out women for sexual company and intimacy, and men who opt to share that sexual company and intimacy with other men in certain circumstances.
