Since the Cialis ads started, I have wondered why are they in bathtubs out in the middle of nowhere?? Now I found this, which asks the same question.
Some of the comments are pretty good.
"Cialis gave the guy a 4hr woody, he is takinmg a cold bath to try to bring it down after they both were exhausted from 30 minutes of heavy sexual activity. The lady is in a warm bath of couse trying to sooth the soreness she has from the same activity."
