the structure of the pubical hair is different than the one on the head, therefore using shampoos and conditioners will not have much effect, the first feeling of conditioner being applied onto the pubes might be something like feeling more silky and smooth, the soon as you rinse it will be just like before. on the other hand using regular showergels and soaps is not reccomended, there are special "intimate zones" soaps with low pH level (3,5) which can be used instead. as for the uncut guys, soaping below the glanse and below foresking is something one should not do as it will remove all natural skin protection and make you more vulnerable to std's like NSU. just rinsing with good amount of water should do the trick. towel yourself dry is important too because all the water residue will just make a perfect skin for the bacteria to go crazy.
