ok just me ?  when i am soft and say no viagra ...  and i start masturbating say to Alexandra Snow JOI videos .. i get close to cumming super fast even though i am not that hard ... well lets say just firm and hard to not pop ...  but if i were very hard ( usually with viagra)  i can be very very hot and aroused and would love to cum but can pump away and total control of not popping.    

Perhaps you might have a case of Viagra Dick.  It's happened to me a couple of times.

She explained that clients who take too much sildenafil get very hard but cannot achieve an ejaculation. The key is to start with a low dosage and find the right dosage that works and you are able to cum.

That happens with me sometimes too. When you get rock hard you may be able to last longer. Many consider that to be medication benefit assuming you do cum eventually. If it's taking too long change positions and/or get some more oral.

Some people simply can't follow instructions!

Or is it that the viagra puts us in new territory. I mean it is likely that stimulation will decrease with time. So if you stay hard longer without cumming then you are getting further into the period of less effective stimulation.

hi everyone .. i think Gnubie is closest to me ...  without viagra ..  if i or my partner starts stimulating me .. i only get moderately firm but would still pop very easily even if i didnt want to.  

If I take my usual 20mg of Cialis, I can maintain the Dino Dick™ at full speed for quite some time. However, achieving an orgasm is occasionally elusive, no matter how much she (or I) try.
