Hello,Sometime I put plastic bag (the normal transparent ones 1 liter http://www.cupsandboxes.eu/roll-polybag) on my penis when I watch porn for a long time to avoid getting pre-cum on my panties or when I finish, for the same reason. Sometimes, I keep one and the same bag for days (e.g. 3-4 days) and only take it off when I pee. I don't use any rubbers or tapes to keep the plastic bag staying on my penis, just making a knot with the bag, because I don't wanna risk do strangle my penis while sleeping.Right now I am having a 4 days old plastic bag on my penis which is filled with small amount of pre-cum.Do you think it is dangerous to keep it for such long period of time? So far I don't see any damage. My penis is just little bit wet and smelly but not too bad.
