What causes foreskin shrinkage and when pulled back for cleaning there are little tear marks that bleed, but not of sufficient flow to bother, I use Neosporin sparingly to stop the bleeding and also to soften up the foreskin. This has only started in the past few weeks, since I took a shower and used a different soap to wash and after cleaning the penis with the foreskin pulled back there was not problem. The next day is when the problem started. Any ideas?
