The sexologist treat the erectile dysfunction. A good family physician also can treat the erectile dysfunction. There can be very simple treatment for the erectile dysfunction. It is almost always effective in recent onset erectile dysfunction. You have to tell to your partner that the physician has advised you not to go for the sexual intercourse. The foreplay is aloud as usual. That includes making each other naked and fondling the private parts also. You can do every thing else but penetration. That solves the problem in most of the cases, say with few days. Most of the time on day one only. You need to be free from the domestic worries. You should have the complete privacy. You should have complete security in the sexual relations. The sexual intercourse is not a act to be 'performed'. The sexual intercourse is the act to be 'enjoyed'.
The correct specialist for dealing with the men's genitals is a CLINICAL ANDROLOGIST. Clinical Andrology is a sub- specialty area within both, urology and sexual medicine. However, all urologists may not have interest or training in clinical andrology because urology is a vast specialty with many sub-specialties. Similarly, for sexual physicians, andrology is one of the many aspects of sexual health that they have to deal with. Then there are also the LABORATORY ANDROLOGISTS. These specialists generally work in infertility labs, processing sperm etc., and don' t deal directly with men's diseases, per se.
