The dominant theme for cock caging/pegging seems to revolve around submission/emasculation. But why?

That's my personal view obviously. But from porn to written erotica, in my experience, cock caging and pegging themes tend to fall towards humilliation/emasculation scenarios.

Which I find strange.

Those are things I enjoy and tried in real life. It had nothing to do with that kind of setting.

I spent a week caged and it was one of the most sensual times of my life. The attention from my partner, the daily care, the maintenance, everything led to a very sexually charged week. If I was "deprived" of that part of my body, so was my partner.

And the same with pegging. We both enjoy anal play. Plugs, dildos, etc. Pegging sort of came naturally from it. I enjoy it and my partner really enjoys getting me off like that.

No humilliation, emasculation or anything like it ever involved.

What are your thoughts on this association?
