For males, erectile dysfunction can be a delicate issue. One medication used to treat erectile dysfunction is Kamagra. The medication Kamagra is combined with sildenafil citrate. During sexual activity with a female partner, sildenafil citrate helps relax the muscles and increases blood flow to the penis, which is good for maintaining or getting an erection. The Kamagra Review is available in our store. This medication is administered either 30 minutes or 1 hour before sexual activity. This medication takes four to six hours to take effect.
