I am 26 year old suffering from nocturnal emissions for the past 7 years, now my penis size is small and soft suffering from sexual weakness?

Educate yourself: Nocturnal emissions are normal and healthy unless you bring yourself to orgasm during the day by yourself or with a partner. Most men enjoy them. If you have 3.0 inches or more you can satisfy yourself and most partners. If you aren't getting hard erections several times a day, get with your physician to rule out an organic cause (prolactinoma, hemochromatois, others).
