20 year old mental issues

My 20 year old son was a very outgoing, loving, smart child until his teenage years.Very early on although he could read and write fluently at 5, we noticed that he has some processing issues very often asking to repeat spoken sentences, and apparently he didn't clearly understand what he read. At 10 he was diagnosed with autism, a diagnostic we didn't really believe. He was always very quiet after school, and later I found out that he was bullied and often rejected my his peers. he had the same 2 friends until the end of High school, terrible low self esteem, struggled though school and dropped out after the first semester in college. during school the 3 girls he was attracted to broke his heart.As a typical teenager he started rebelling and answering back even when he knew the consequences (he would lose his phone)to this day the situation has only gotten worse. he is extremely nice to strangers but to us (parents) and younger brother he is very negative and mean. Gradually he has developed dislike for women, his girlfriend (who leaves overseas) seem to be annoying him every time she texts him something nice. He cannot stand when i call his name even to come and eat. He made a few comments about women being inferior to men, and lately he spends a great deal of time online chatting with men in a sexual way. he is lazy, has no motivation for anything in life except to make 'Friends' he grew up with a lot of love from both parents and extended family. this level of negativity is very toxic I read about Sepia (aversion to family members) as well as aversion to women (pulsilla,and platina) but i am not sure wether or not they ca be taken together . He started acupuncture as well, sometimes he is negative for no reason (most of the time) its such a horrible situation, in the past i also tried Neuro-feeback, counseling. nothing works.
He has no sense of danger (meeting people online and driving to them ) I need help , can someone advise me. I rather ask here because anywhere i go and mention my son's attraction to same sex i will be looked at as a hateful person, which I am not. thank you .
note that he sleeps late at night, has bags under his eyes, spends his life in bed, 5.6, 140lbs, never any major health issues goring up, very happy as a child.
