I really don't know about forced feminization. Oh I love BDSM and being submissive and it was never forced onto me.
Look. There are plenty of men and or women that like femininity. Being tied up and helpless is a little different though.
Look, fantasies are one thing but finding someone that will love you and understand is a totally different thing. I love being tied up and am free the be femme and he spanks me with my own hair brush at that. I tell him harder or not. Sometimes I say, "->-bleeped-<-, that hurt so stop." and he does. Sometimes he uses a belt on my ass tied down spread eagle but just on my butt.
LOL I love bondage but it goes both ways so a safe word or and understanding is so important so make sure of that.
No one has to force me to be feminine male of female. Well now it is only one man but he knows my limits. He pushes then and I let him even but when I say stop he does.
OK so I may be gay even though I am femme because I love guys.

Hell all my gay friends call me gay but I am not. I am trans and they really can't understand that. But my boyfriend does though and that is all that matters to me.
Look. Just be you. Do you really need anyone to force you to be feminine? Yeah is sounds nice but... Just be feminine and if you like BDSM then big deal, it is fun to feel helpless and not in control.
