Why there is a so big sexual difference between doms and dommes ?

why are sexual dynamics so different from doms vs dommes? every day I see dom posts and there seems to be a lot of sex of all kinds and a lot of orgasms on both sides. on the other hand when I see posts from dommes it's always about chastity, using dick as less as possible, preventing the submissive from having orgasms and leaving him for months without using his penis. I know very well that there is not only the penis to have sex but why not use everything that is available. I also see a lot of dommes not having sex with a penis but doing cockolding to have sex and that the submissive is not allowed to see another woman, but on the dom side I never see anyone say he do cockqueening, that he has a submissive to whom he does not give sex but that he is going to fuck someone else and that she has no right. I would like to understand why there is such a big difference on the sexual side. This is really not a bitching post, I am very interested in the psychology behind the different dynamics and I base this on the posts that I see on different reddits every day. Thank you for your opinions in advance.

Edit. Another difference is daily task. When i see dom it is always for the sub to be more healthy and better person, like drink water, brush teeth, eat 3 times per day and other things like this. when i see task ask from domme it is always task for the domme like prepare coffee and diner for the domme, house cleaning task and a lot of feminization, no task for the healty of the sub always only for the pleasure of the domme. its really two different way to do things. Maybe post are not representative of most of the real domme/sub relationship too, i don't know.

Ps. Dont know if i can ask but if domme want to explain to me why they have this kind of dynamic you can dm me i will be very happy to talk to you and better understand those kind of dynamic.
