A lot has been written here on this fine website about Viagra and Cialis. I guess I wanted to regurgitate my experiences and compare them to others.

When I take Cialis, it seems like I am superman so to speak. I can go at it multiple times over a period of 2 or so days. I get a hard on very quickly. However, I never seem to cum when I am on Cialis. After taking Cialis I get a certain tightness feeling in the head.

When I take Viagra, it doesnt seem to have the same effect. I get an erection with Viagra, but its not as intense as with Cialis. I can cum while on Viagra. I dont get that same tight feeling in the head.

I am not a doctor or a scientist so have no idea what factors are involved here. These are my honest experiences.

I'm pretty sure that the experiences you're reporting with these drugs are just about opposite to what most men report and 180 degrees contrary to my own experience.

I think most men report experiencing more intense erections with Viagra than Cialis. With C you sacrifice some percentage of maximum dick rage in return for the 24-36 hours you get to raise just enough wood whenever you need it.

Most guys I know say they more likely will get headaches from V than C. C though is now demonstrated to cause backaches in a percentage of users. Fortunately, I don't get side effects from either other than sinus congestion when I use V and that applies to Levitra as well.

Probably both drugs cause some desensitization but if you can't cum it may be due to endurance humping which I believe causes desensitization in itself - does with me anyway. Sometimes I have to fight back that near inevitable urge to cum in the first 15 seconds, but when I beat that compulsion I'm in control forever but my urge to cum diminishes the longer I go at it. Other than that speculation the problem may be in your big head or maybe you're just not getting enough of the kind of strokes you need.
