Sleep disorder. But nothing worked.

I am not ready to consult a doctor in person so looking for an online one. recently for the past few months, I am facing a problem where I get little sexually excited in sleep and unconsciously touching the person next to me , mostly private parts and sometimes even groping. irrespective of the gender. I once did this to my cousin , he told me about it , then only I was confirm of this behaviour and I am straight .most of the time I realize only the next morning that too little vauge, I did something like that , few times I have realized immediately while doing it but still I made myself to continue as it felt like its a dream, I don't know to explain clearly , but this is my problem , I am now afraid to sleep with someone else because I don't want to damage my image. is this curable , I have tried many things , meditating before sleep , chanting slokas but nothing worked. I am not having any orgasms or that sexual feeling but i cant control my actions while doing it. please help me.
