For full disclosure, I feel I have to let you all know that Peyronie’s Disease can also be caused by a build-up of plaque on the Tunica. This build-up (typically along the top of the shaft) prevents the Tunica from stretching, thereby causing the curvature. There is no connection between this plaque and cholesterol levels.
However, it is believed that the plaque is actually scar tissue – from minor trauma, tears, and abrasions over a period of time.
Here’s a link to a very informative website dedicated to Peyronies.
Bottom line, here is this: Treat your cock with loving care! Don’t get too rambunctious when you play with it, or when you and your partner are schtupping to beat the band; don’t let a jack-off buddy mistreat your Mister! If he (or she) does – pack up your package and leave.
