Gentlemen et al,
Something you should consider when you hit that milestone is getting , by less than medical terms, an orifice scoping. I just got the results of my recent "adventure" and thankfully all was normal.
Many problems that these scopings reveal can be easily dealt with if discovered early.
BTW,the "cleansing" prep in the day before is a bit "tedious" but the proceedure itself is completely painless since it is done under general, mild, anesthesia. And they give you some great "stuff" to calm you before and after.
These proceedures, the annual "digital exam" and PSA blood tests should be done.
Remember, you're only invincible on the waters.
