PE as an uncut guy
Are there any videos or instruction manuals on how to do PE as an uncut guy because I feel like all the videos and instructions that are already in this website are only for those that are cut. For manuals, I retract my foreskin and grip behind the glans but I just end up slipping over and the times I do not slip, I seem to put too much pressure on my glans because they turn white (I think from cutting off the blood circulation) and sometimes also turn dark colored. However if I lessen the pressure, I don’t feel a good stretch in my ligs. Can anyone that is uncut and successful with PE provide any tips?
