As-Salamu Alaikum.
I got married 4 years ago. At the wedding night, my husband told me about his physical problem that he is dealing with erectile dysfunction. He was unable to do anything physically in the first two months.

After he tried homeopathic medication which helped him and we had only 2 months of physical relationships which lead me into my first pregnancy. I delivered a baby boy.

After those 2 months of
physical relationships, it's been 3 years now we don't have any physical relationship. Now neither homeopathic medicines nor the doctor-prescribed medicines work for him.

I'm totally depressed in this relationship. My in-laws are suppressing me to continue the relationship for the sake of my son. I don't know. I may end up in committing a sin.

If I divorce this man, I don't want to get married again. But the presence of this man in my bed every night makes me more depressed. My mother in law told me to satisfy myself by other means.

What should I do? No one wants me to go for divorce just because I am sexually unsatisfied. Please guide in the light of Islam.
