Viagra is a prescription drug for ED and while I am sure it can and is obtained illegally (or even legally) by some, why would a provider want or need to supply it?  The client pays for her time whether or not he gets it up, or finishes.  Unless perhaps she is looking to extend her time for more cash?  I dunno.  Never heard of providers dealing Viagra or Cialis but I guess its possible.  The health risk for those with high blood pressure taking those meds goes up exponentially, she might end up w a heart attack victim with an ambulance to her incall rather than a sated client.

IN a lot of cases Viagra takes and hour or more to kick in. Just from a logistical standpoint it doesn't make sense to get that from your provider, unless you want to sit around and shoot the shit for a while.

It’s so easy to get it legally from a doctor, why would you want to get it from a provider?
