While I think it is healthy for all men to really explore their sexuality including submission since "acceptable" male sexuality is pretty limited. This should really include finding who you really find attractive besides the "perfect" photoshopped woman display in magazines and other places. I think exploring things like BDSM even if you aren't interested in it can give a lot of knowledge about pleasure centered sex that isn't PIV focused. However, this implies that this itself is a liberating act that leads to:
relinquish the societal norms of “masculinity.”
The powerful executive who is into submission in the bedroom is a cliche since it is so true. These people don't relinquish societal norms of masculinity but rather support them everyone except with their pro domme. These people also usually have the traditional Madonna/ Whore complex where they can only get sexual satisfaction from their "whore" but could never bring this up with their perfect "Madonna" wife or girlfriend. It takes applying these lessons to your day to day life and your relationship for it to be meaningful.
