So I had the opportunity to be involved in a university discussion on this fashion topic. Whether men wearing panties(made for either gender) is a sign of pervercity or just a broader than normal fashion sense. So my take is that it depends on the reason why the guy is wearing panties. I personally have a hard time with boxers because they twist around my leg and restrict my hip movement. After years of ignoring this I now have hip problems. I feel if someone in my situation wore mens or womens panties that, however weird and unflattering it may be, that it would be totally fine; same thing if they are worn for exercise or strictly for comfort.
Comfort is important when it comes to clothing, we all know this even if often we ignore our comfort.
In this discussion our class heard several different perspectives from many different people. One point of view stated that mens boxers are "Uncomfortable, allowing the genitals prolonged contact to the inner thigh, causing chaffing, 'swamp crotch' , and awkward movement." This student argued that these problems including "swamp crotch" (odorous bacterial growth due to excessive perspiration) would be fixed by wearing panties as the garment would, depending on fabric, allow the wearing greater ventilation to the area, a different form of support for the genitals, and a well formed design provided more comfort. The student also gave some cons to his argument, mainly a public stigma of the practice, dreaded pantylines for some fabrics and designs, and the effect on sperm production.
This student did not admit to participation in this exact subject but promoted an appeal to reason in favor of those who do for practical purposes.
An opposing student based their argument not on any religious view(which was discussed and cited in religious text at length as well, concluding that the main point of argument as theologically moot by later religious text) but on a view based on possible sexually deviant reasons for the choice of vestment. The opposing student stated "I agree with (name excluded) on the basis of 'comfort, and preference' but however if the panties are worn for a sexual purpose I object to this. If its a couples sexual practice, who cares what goes on in the bedroom 'dont ask, dont tell' all the more to yall! If the wearing of the garment type in question involves a lone man who just is sexually aroused by wearing underwear like that, then its weird, If he stays home like that who cares! Although if this man goes in public in a state of sexual arousal then the line has been crossed, he should stay at home for that, and the purpose for wearing panties has been changed from a practical to a perverse reason."
Of course any man willing to wear panties whether in private or public is making a fashion statement, these two students made great arguments and stated others such as cultural tradition, popular preference, and change of fashion trends.. Overall the subject is left up to the individual whether the stigma of such a practice should remain. I as an individual think we should remove the stigma and be more accepting and less judgmental of those making a rather odd fashion choice as this.
