Question

and how many times should you do it>

Answer 1

You should only have to use one condom during s*x unless it tears or you change partners.

Answer 2

Oh brother, do you really need people to tell you how many times you should "do it"? How long is this guy lasting anyways? Is he melting the condom off or something?  

Answer 3

Condoms are meant to only be used for one session of s*x. You do not need to change them unless you are having s*x more than once.
