A friend has told me that he has been raped.
That must be about the greatest level of trust a man can show towards a friend. The level of shame and guilt surrounding male rape is enormous, it's the sort of thing that flies against all the male - macho thinking. In our minds we can deal with 'anything' and fight off any agressor. The truth is somewhat different.
The most imprortant thing for you now must surely be "don't blow that trust"
He told you because he trusts you, and because he thinks you can help. Maybe he doesn't know what the 'help' is at the moment ? but when he does he's indicated that he wants you there with him.
If you drag him along kicking and scraming into therapy, then there's a big chance you could alienate him. Most of us start healing when we're ready, and no sooner.
"Be there" for him, suggest things by all means, but don't tell him what to do, just point out what's possible and available. What we thrive on is SUPPORT for what WE do.
You've shown already that you're willing to give that support just by coming here to find out what's going on in the world of a Survivor, and keep coming - we're pleased to help where we can.
What you're embarking on isn't going to be easy,but don't let that stop you. The rewards of recovery are worth every scrap of effort.
