Hi, I am 24, m. I have a serious family problem at home for the last few years. My dad and mom are 57 and 51 years old now. I see my dad has lost libido totally in the last few years and mom is not. This has caused serious problem between them, rising fights every now and them. I started understanding things recently it's because lack of sex between then. Recently my mom starts to have some affair with neighbour uncle, which I am not sure to what extend it has gone. I real need some help or advice from doctors. I can't go discuss about this to my parents. Any medicine to my dad? He doesn't take any medicine even if he falls sick, especially allopathy. He is free from diabetes and BP. Healthy living and active too. Please suggest me some medicine and its effect. Thanks.
