I am a 31 yrs old male. I have been married for about 2 1/2 yrs. We love each other very much. As we both are very busy, there are very few days we meet in a month. But the problem is that i am having problems in having an erection recently, not always, but sometimes . Though i do not have any known diseases and my job isnt that much stressful, i am becoming very much depressed. Is this a normal ?
