A lot of what you find online is crap, but femdom or various domination fetishes can be very good.
Online you find nonsense like humiliation, chastity, cuckolding, and a lot of other nonsensical crap.
Most people would not be able to practice it properly at deep levels, they would end up exploiting you.
Domination fetish is a way of worshiping your partner and giving them power over you. This should be taken on a constructive path, and not unnecessary slavery.
This practice should not reinforce any imbalances, but it should strengthen the bond between the two people
I would only trust a Goddess for such a practice, I would not trust any human being out there, would you trust a human being to hand over your existence, your soul, body and mind?
If you are talking about one-night-only experiences instead, think about it.
Femdom would lose its meaning.
As for the central point, domination fetish will not make you less of a man.
On the contrary, worshiping your wife with body and soul will make you more of a man than before.
This practice if done in the right way and with your partner (which in my opinion should be eternal), is one of the most noble and sacred things there is.
The rest of the world has a wrong oppinion (I'm reffering to the fetish comunity, and not to the "normies"), only a few practice it with heart and soul, the rest just have itchy dick. Those few who do it with heart are limited by it, because of the human aspect in it all.
With a Goddess there are no mistakes, true femdom you can only experience with a divine being.
It is complicated to explain, I hope you can understand me.
