These days I don't keep my foreskin back when my cock is 'resting' I find having exposed glans rubbing on clothing irritating.
It will stay back but often it will slip back over the glans, I used to use a trick to keep it back by working the foreskin cock erect with short strokes behind the glans, making it sort of fold under itself, them let the cock go soft with the tight ring of the foreskin behind the glans some of the foreskin tucked under forming a sort of ridge behind it.
