I have not read every post so sorry if others have said what I am about to.

I would recommend that you start out slowly. At first just look for someone or a small group that you can have good, honest and open conversations with. As you find greater comfort with a group you will also eventually find someone who connects with you, knows you well enough to not be deterred by your difficulties and truly likes you for who you are, not who they think you are.

I found that I had to reenter social life slowly after my wife died. It took years to build back up to being able to have another romantic relationship. I will also be honest about that, I have not always been the "boyfriend" that I want to be. It has been a bit of a struggle but she knows of my difficulties and is excepting of that. We have taken things slowly, gradually increasing to higher levels of emotional and physical intimacy.

It is a long process but if you try to rush things you really are only going to end up with more stress, more frustration and a failed relationship. Such a thing will do nothing more than hurt you and the person that you wish to spend time with.
