Masturbation and foreskin. Hi. I’m 21, and I’ve never had intercourse. I don’t have any problems with getting my foreskin behind the glans, either while flaccid or erect, although I believe I might have a slightly short frenulum, since my glans bends downwards when I retract further beyond the head, both when flaccid and when erect. English: In this video is demonstrated how a foreskin of an uncircumcised penis glides over the glans penis during masturbation. The video is taken from different angles. The male (age 35) seen in this video moves his foreskin back and forth over his erect glans penis by three fingers or by whole hand, no lubricant is used.
