a man goes to his doctor "doc, I'm worried. I had sex with my newlywed bride 3 times last night!"
the doctor goes "oh, thats not a big problem, many couples have lots of when then first get married. don't worry about it"
a week later, the man returns to his doctor "doc, I'm worried. I just had sex with my wife 5 times last night!"
the doctor is surprised "wow, thats alot, but there is no reason to be worried yet, you are young and healthy. I'm sure you'll settle down with time"
another week later the man returns "doc, I'm REALLY worried. I just had sex with my wife 10 times last night!"
the doctor nearly fell out of his chair "oh my god, how is that possible!!!??"
the man said "it wasn't difficult" as he thrust his hips and started counting "one...two...three...."
