I have used Kamagra a few times...for the hell of it. But the thing is, after you climax (if you're a guy) you still feel like you're done now and want to hop right into the shower and get dressed. Only thing is the boner stays much longer after you're done. Just like Maximor, it wont make your staying power any better (in other words, it won't improve your 'endurance'). Only practise does that So what's the point really.
