You mentioned masturbation. I take this opportunity to ask a question, even if it has nothing to do with the issue that is being discussed and therefore I risk going off topic. However, I try anyway. Although I often read it in the comments, I never understand exactly what is meant by the statement "masturbating with the glans uncovered". This is because some refer to masturbation with the foreskin that fully exposes the glans and remains under it, while others to the stimulation or direct touch of the glans. What would be the right and exact explanation or definition ?
