i don't really know what to expect.
Welcome. You can expect a group of guys who "get it". Guys of all ages who have had experiences and feelings similar to yours. Guys at all stages of recovery who you can learn from. Guys from all nations, of all sexual orientations and experiences, who despite our differences, will support you and whatever you're going thru.
You are courageous to be dealing with your CSA at 26. Many of us kept it bottled up till much later in life and have wasted many years trying to deaden the memories with alcohol, drugs, sex, and bad relationships. You have the opportunity to create a life as a whole healthy man. Go for it!
"Carry on my wayward son
There'll be peace when you are done
Lay your weary head to rest
Don't you cry no more"Kansas
