After 2 years of married life now I am suffering from sexual problems. Lost all my confidence as a man. My sexual parts is not functioning properly at time of sex. At the time of sex my penis is not becomes hard, some times it becomes hard but takes very much time to make it hard & this creates problem for me also. If I use protection at the time of sex my penis degrade small in size quick it not keeps hard which I want too. Then I have remove the protection goes for masturbate to make my penis hard. Same things is also happens without protection also. However my penis size is also very small. At normal time it remains 1.5 inch & at the time of sex it becomes 4 inch. I believe this was not the normal size for an Indian man, I have checked from Internet & found that normal size was 5 inch for an Indian man. So I want to make my penis size big & hard during sex. Me & my partner was very Unsatisfied for my sexual issue. Please suggest the better treatment for my sexual issue.
