I want you to help me out with a problem that I am enduring right now. I have been married for 10+ years with two kids. My husband has been suffering from erectile dysfunction for quite sometime and we had gone to a sexologist who suggested some routine tests and a penile doppler but the doctor had said that everything was normal with him but gave him Sifasi 5000 IU and asked him to inject it once in three days and also gave Arginitric to consume daily. This happened two months ago and he has been taking the meds off and on. The problem is that he still has the same problem and is anxious most of the time. He has lost interest in everything and he does not like to spend time with either me, the kids or his dog though he claims most of the time that I do not spend time with him. Last week he lied to me and spent time from morning till night with a colleague of his with whom he worked five years back (unmarried girl) and had gone to a film, restaurant and ECR and when he returned home at 10 p.m. I questioned him to which he said I did not have any right to question him. We had a fight and from then he is not talking to me. I want to know what his problem is and why he did such a thing all of a sudden. My kids and I are very upset because of his weird behaviour. Please help.
