Sorry, perhaps I misunderstood. I thought the question was whether a Dom and a Domme could make a good couple ....

Now I understand the question is "why do doms keep harrassing dommes" ...
well I can't say anything about this ... I did not even suspect that this happens so commonly ....

The only answer I can think is "because there are a lot of idiots around"

Someone may think that every woman MUST be a potential slave, so that there is a special challenge in trying to enslave a domme .... and this is already stupid ....

... add to this the fact that some individuals feel they must harrass any woman they come across and a domme is something "kinky" so it's even more compulsory to try hard ....

Of course there might be some chance that a Domme could have also submissive inclinations, esactly as someone pointed out that a Dom could be secretly looking for a mistress who may submit him .... there might be a chance, but it surely is not very likely.

I remember a Domme I met and who enjoyed my slave who suggested more than once that I could enjoy playing a submissive role with her, what I refused everytime with a lot of amusement.... I am not interested in male submissiveness, generally speaking and in myself as a slave in particular.

Anyone who speaks about "breaking" a woman into submissiveness only proves that he has very little experience and knows very little about women.
