I think their is a middle method/option that is nurturing and also 'degrading and humiliating.' i'm totally turned off and shut down when a guy is mean (i'm gay), forceful, bullying. Any of those attitudes or approaches make me feel like the Top/Dom is compensating, and it feels the opposite of control for me (i understand, this is just my perception, not implying my response is some sort of standard, i know there are plenty on both sides of the slash who want those).
For me, a gentle, affectionate, encouraging, "nurturing" approach has a matter of fact feel to it. I.e., the Top/Dom doesn't need to force something that is already there, rather, they are evoking and controlling it. To me, that is a sort of penetrative mind fuck that goes beyond force. For me, it is particularly powerful if a Top/Dom is simply acting from how He perceives me, not trying to 'make' me into anything, while wanting to evoke and control what He believes is already there.
i think something else that is often confused or missed is, for some, feminization is can be a method of emasculating. I.e., it's not so much about the guy becoming fem as it is losing or acquiescing his masculinity.
i think feelings of shame, embarrassment and the subsequent feelings of degradation and humiliation are conditioned emotions. Culture conditions guys, directly and indirectly, from day one on how they 'should' be (i.e., masculine), and departure from that gets a response that conditions one to hide, etc..
i subscribe to the spectrum theory of human sexuality. On a spectrum, there are infinite variations and degrees one might be 'wired.' I've experienced where a guy both sees and wants that about me, and has a lust/need to have that in me. When that happens, i get very aroused and feel simultaneously affirmed, and at the same time experience those conditioned feelings of "degradation and humiliation," that i do not associate with hurt or pain, but are also deeply arousing given His obvious affirming desire and even need.
