Why do I not get aroused again?

Q: As soon as I ejaculate after intercourse I lose interest in sex and I want to sleep but my wife remains unsatisfied and I get very embarrassed. My penis also loses erection and I am unable to do it again, is there any medicines so that I can get aroused again?

A:For males, it usually takes half hour to three hours to get aroused again after one intercourse. That is a normal phenomenon. It will be better if you get yourself investigated for erectile dysfunction so that you can sustain your erection for longer duration.
