I also am interested in taking castor oil for experimental, entertainment purposes. Does it make any difference whether one takes the tasteless variety or the traditional version in regard to the laxative effect? The former seems very common. Complaints about the bad taste of castor oil are frequent. Does making it tasteless decrease the laxative effect? If one wants the full laxative effect, should one search for a bottle that doesn't say "tasteless." Also, If one wants to incorporate "castor oil" into a D/s scene, shouldn't one seek the variety that allegedly tastes "vile." Some say that it is the texture, not the taste, that is vile in the traditional type. Will one miss a lot if he takes the "tasteless" variety?
Too, I have heard conflicting testimony in regard to whether or not there will be cramping. Some say that the castor oil had only a mild laxative effect on them. Maybe the effect varies greatly depending on the dosage, the individual and their diet. I had the impression that 4 tablespoons (2 ounces) would bring about the desired result. People taking a laxative out of necessity generally seek to avoid cramping. However, in the scenario I imagine a lack of cramping would be very disappointing. Discomfort would be a goal of the experience.
