I am almost 60 now, and sometimes I am sporting wood after 15 min, even while taking the subway to the appointment!  Recovery time for round two is down to 10 min.  I have initiated round three around 45 min into the hour a couple of times, was rock-hard but my system overloaded and I did not complete.  Both times, the girls thought I was gonna die!

try looking up marin medical clinc  they have a new thing that get you hard for how every long you want one hour or two if you want. you can shot your load and still stay hard and ready for round two right away and stay that way till the time you requested is up

I get the stuff from a $ for a $1 20 to 30 pills if some off brand but if you take the whole bottle it works ok And I dont need a docker

The entire story......................................

Cialis lasts up to 36 hours,  Viagra up to 10.
They are the same basic compund. (PDE5 inhibitors)  Sometimes one will work better than another for different men.
They do NOT prolong ejaculation, in fact studies have shown viagra useful for helping guys that take too long to ejaculate easier.
Cialis is LESS affected by food or drink than Viagra
NEITHER does anything for recovery time.  they are basically a one shot deal.....if you recover soon afterwards, you did it on your own, as there is little active ingredient left in your bloodstream to help with another erection.

Believe me...I know of what I speak!

Best bet, get the doc to give you a script for each.  See which gives you the desired effect, and then use it.

I have used both of these and Levitra.  
All will help with getting and keeping an erection.
I think Levitra worked the quickest.  Both Viagra and Levitra last about the same amount of time (one pill lasted all evening and still had some effect the next morning.  Both of them gave me a big problem with flushing.  

Cialis took the longest to take effect but lasted much longer.  One pill Friday night would be all I needed for the weekend.  I had no flushing or other side effects from Cialis.

I didn't notice any difference with recovery time between the three.  

In my opinion Cialis is the way to go.  But I had to be insistent, to get my Dr. to proscribe it.
