An 80 yr old man just got married with a young wife.
Fearing with all the sex that he is having with his new bride, he seeks Doctor's advice on the best way to deal with it.
Oldman: Doc, I am 80 and am sexually active again. What's the best way to have safe sex without getting heart attack...??
Doctor: At your age , I highly recommend you to use 'The Dog Style'...
Oldman: Doc, are you serious?? My back is weak.. How can you advice me to do Doggie Style?
Doctor: I said Dog Style... not Doggie style. Dog style - just sniff the pussy...
