Are Most Men Doms Only Looking for Women?

No.
Regaurdless of how the world see things you first have to specify by definition what a 'male' is. Then considering the multiple sexual orientations that clearly define someone's gender simply by what they say about it anyone you might jot consider as 'male still could be. On top of that the majority of ppl id say are 'male' are simply ubber-doms left over from sex sites that either didn't want them or didn't last which left them to us to take care of and those individuals aren't dominant and dont just want women, they just want to get off.
