Can i use cialis and do sports at the same time ? it wont hurm my body? i have erection problem because of kegel exercise what tests should i do ?

It's OK: In fact, cialis, viagra and levitra (vardenafil) have all been studied for exercise performance and there is some suggestion that they can decrease the time to achieve peak power with exercise. It shouldn't necessarily harm you any more than it would for a non-athlete. There is limited evidence that Kegel's cause erectile dysfunction. I would seek the input of a urologist to help you out.
