I tend to use 5-10mg Cialis with WGs only as I don't need it with the OH. No side effects and a reliable boner. I tend to get an immediate boner after the first pop, which however tends to subside at some point without being able to get pop 2.
That I find strange because at my early forties I can do 2 pops in the same hour with the OH without Cialis. Having said that, with a WG when not on Cialis, I can only achieve 1 pop and then I get floppy with no chance of another hard on... So it seems that it gives me an immediate second round, but little chance of a second pop. I will try the full 20mg pill next time to check the difference.
