The thing is that if there are serious issues with your personality that keeps turning away people you want to be interested in.....then therapy would be a good place to start. Neuropathways in the brain can be reprogrammed with a lot of practice & mindfulness to be away of what it is that you are doing that is turning people off.

Having Sex & having relationships is not anywhere as important as self improvement so that you can have truly meaningful relationships.

I left a marriage after 33 years....it was bad. I am still NOT divorced at this point but it's getting closer....the thing is that I do not choose to get involved in any other relationship in the future unless some wonderful person comes along & is truly everything that my marriage wasn't....I wouldn't waste my time on anyone for sexual reasons or any other reasons. It's taking me time to truly sort through who & what I really am after all those years also & I need to fix a lot of broken things in my own life & rid myself of all the anger & frustration that built up over all those years. Focusing on myself & becoming a better person is much more important than finding someone else to have a relationship with.....think that might be true in your case also.
