I agreed to do this way back then, and I have no problem with it. You see, I love my wife and this is a small thing to do for her. My masculinity isn't threatened in the least.
In fact, my masculinity isn't wrapped up in any of the associated subjects we're talking around on this thread.
OKAY then! ;~D
I guess in the long run, the best policy is closed doors.
Ask her if the last thing she wants you to do before you come to bed, is dip it in the toilet water.
