Haha, actually Swim
has. Although, instead of the Viagra it was Levitra. Ok, here's the deal.
The Viagra will obviously keep you "going" for as long as you or your wife find neccesary.
But keep in mind if Swiy takes enough Hydrocodone
(for swim 30mg would do it), then he will have difficulty climaxing.
So if Swiy wants to give the wife a great night then it would definately work out to her advantage, but as for Swiy himself...just be mindfull with the hydrocodone.
The more swiy takes, the more difficulty he's gonna have..."finishing"
Have Fun. And don't play russian roullette with the whole not climaxing deal. Wouldn't wanna be responsible for an unexpected addition in the family.
