I am only 29 but often I cannot achieve a full boner when I am with prostitutes. My pecker expands and becomes somewhat hard, only to become soft again and insufficient for penetration. This has become a real problem for me in recent years.
I have always been a chronic masturbator. For much of my life I have been a total incel, not because of my physical appearance (I have always been athletic and in good shape) but rather because of my social anxiety and my inability to fit into society. Now it is as though I cannot keep a full boner unless I am jerking off by myself and living in my own fantasies.
What can I do to solve this problem? How can I keep a full boner during encounters with prostitutes?
