Anybody else get a really great boner about three or four hours after the date. In other words, six or more  hours after dropping the pill?  It's happened more than once.

after 2 hours of pleasure and the drive home something sexy pops in their mind and "oh shit". Not a good thing to happen when you haven't had sex with your wife for 10 years or so. I was told that one of the drugs these gentlemen take can last up to 24 hours so buyer beware. Sexy thoughts, daydreams or just a brief sensual visual in public can be very stimulating to say the least. I don't remember the brand name that lasts that long but maybe someone else can ad that here.

I have noticed that the effect of the pill lasts for quite some time. Up until the next day sometimes. But there has always been some form of stimulation associated with it. Having a drink at a strip club or remembering the session will cause an erection. I've never just had one for no apparent reason after taking the pill. I attribute it to the dilative property of the medication being long lasting and effecting everyone differently.

after a romp the night before.  I think there is some in your system for 24 hours.  Wifee will never know as there's a 3 foot no-man's-land in the middle of the bed.

Lasts for at least 24 hours-but as was mentioned-requires some sort of stimulation.

There is a reason that Cialis is called the Weekend Pill. I do not like it for that reason.

I cut a Levitra or Viagara so I get a little buzz - a little help, just to make sure. A diminished boosting effect does last into the next day.
