loose foreskin
Foreskin which is visibly loose. This means that it will hang away from the glans naturally, or will produce wrinkles under its own weight or in some positions. Often produces large, relaxed wrinkles that circle the entire penis.
Not to be confused with wrinkled_penis, where the entire penis has wrinkles. Whereas this tag necessitates also having foreskin, with preferably some of it hanging loose under its own weight.
