Realistically I don't know anything about this. But I noticed you had yet to receive a reply to this post. So I thought I would write one.

My only thoughts, with regard to what you wrote, are that perhaps this is a symptom of depression? Or, in the alternative, perhaps you simply haven't found the right partner... yet? I would guess having your only sexual activity be with yourself would become boring, frustrating & empty after a while.

Hopefully there will yet be other PC members who will have more insight into your situation they can share.
