I am going to assume your refering to real life partners and not an online "relationship" situation, cuase with the later I would just tell whoever that was to take a hike myself.
If this is a real life thing...it sounds to me like your finding dominants who are eaither inexperienced, or under some kind of illussion that you shouldnt touch yourself or that you shouldnt ever experience pleasure unless its by their hand etc. Which is plain hoppin fiddle bs when you get right down too it for all intensive purposes, even amongst the hardest core kinksters.
This is ussually eaitherr due to some misconseptions becuase they were self tuaght via the internet or they are simpley unimaginative and cant get past using CR as a defualt setting with any submissive they get or its their prime fetish.
Dont get me wrong; normally cum restrictions and touching restrictions are useful training tools for limited periods of time, especially with a submissive who is at certian points in her training (ussually not right at the start, and later ussually only as a punnishment) or when in an arrangment used as a way of increasing arrousal for a short period of time and then going through a cycle of denying relesase and further teasing until a forced orgasm is obtained, which in most cases is accomplished in "scene" or over the course of a few days of repetative contact sessions where one is briught close to orgasm yet not allowed an orgasm, too much time ussually isnt allowed to elapse lest the submissive becomes fridged....unless as previously mentioned its where that is the primary focus of their fetish arrangment.
Such primary focuses of course being under the consideration that all things bdsm should be safe, sane, and ..."consensual".
Consensual meaning that If you simply cant stand having that (no touching etc) as a condition of your submission, then by all means, speak up and set some limits with your partner.
Or find a new partner that is a better fit.
Domination and submission is after all a two way street.
