I am 27 years old and last month I came to know I am diabetic with very high sugar level of 500+. I Started treatment and its been 40 days and my sugar level is now slightly high but I am still feeling a lot of weakness in my body and not able to any heavy work. The more problem I am facing with my sexual strength and my penis is not getting properly erected. Is it a new sexual problem or it is because of my body weakness?
