Can i last longer with viagra?

Viagra isn't going to do anything for you if you can get erections without using it. And for men who can't get erections without viagra they will still go soft after they c um. Viagra will last approximately 3 hours in your system and you can get a second hard-on while it's still in your system providing you have the sexual desire to have sex again. It doesn't increase sexual desire/libido though. If you can stay hard after coming then you don't need viagra and shouldn't use it. The Cialis daily pill might work better than Viagra but I have never tried it.
