Referring to the data emerging from the survey, beyond the predictable large majority of men who retract the foreskin only during the shower (about 78%) and leave the glans uncovered for a short time (more than 54%), it can be noted two interesting results. In fact, against all my expectations:
A) Nearly 22% of respondents say they retract the foreskin before the shower starts. Personally I believed that this habit was much less common.
B) Over 45% of respondents said they leave the foreskin retracted (and therefore the glans uncovered) until at least the end of the shower. Evidently, although I thought the opposite, it is quite common not to immediately cover the glans after washing it.
I take advantage of it to mention the data from another poll like this one (but done on a different website). Among other things, the results are all in all similar:
1) Regarding the "moment of retraction" of the foreskin, the vast majority (66%) do it during the shower, while the minority (34%) do it before starting.
2) A small difference, compared to what is written above, there is about the "retraction duration" of the foreskin. In fact, according to this further survey, 51% leave the glans uncovered for longer (i.e. at least until the end of the shower), while 49% cover it immediately after washing it.
