I occasionally use it if my estrogen/test balance during cycle causes Mr. Happy not to be quite as hard as usual. But in my experience here are the pros & cons:
Cialis: Pro - Erections seem to be of normal hardness and duration
- Supposed to last for 3 days, (usually lasts closer to 4)
Con - Causes a mild stuffy nose, which also last for 3-4 days
Viagra: Pro - Erections are harder, more intense, and last longer than cialis.
(I often retain a full erection even after ejaculation).
- The stuffy nose only last for 4-6 hours rather than 4 days like cialis
Con - After about 4-6 hours, you're done so dosage timing can be critical
My personal preference is Viagra. It turns me into superman between the sheets as far as ability to keep going and going and going... But I REALLY like the fact that I don't have to walk around with a stuffy nose for 4 days with Viagra.
