Where do I begin... My boyfriend just confessed he was molested as a boy by his camp counselor when he was 7. He admitted this to me after I found transsexual porn in my computer history . He said he feels by watching this it's punishment to him and painful . He feels less of a man. What do I do?

Get him into counseling quickly. He does not need to be "punished" for being molested.

Of course he may enjoy watching this, and is lying to you to. In either case counseling.
