First of all, thanks to all the members that posted a reply in this thread, as it gives really a variety of different approaches to this matter, as I suspected.
But then let me try to formulate the question in a slightly different way. This was somehow implicit in my intention anyway…
Most of the replies turn around the effect of suppositories and enemas on the bowels of the writer, as if the matter was considered only in the context of solo playing. Now, I know how difficult it is to find a partner for suppository or enema playing but for a moment imagine yourself having a mate to play with.
In such a situation would you like to administer to him/her a laxative suppository or, say, one for nausea or sore throat? Would having control on his/her bowels increase your excitement or not? On the flip side would giving your mate control over your own bowels increase the excitement or not?
And the same would applies to enemas. If they could be used, say, just to absorb some water, when playing with a mate would you use such an enema or would you stick to the cleansing ones?
Of course, given my OP, you can easily guess that for me laxative suppositories and enemas would always be my favorite and those which would arouse me the most, but I would like to hear from as many esteemed zity members as possible what their preference would be
