There is a place called "Adult Victims of Child Sexual Abuse" in Little Rock DW. I found this by doing a browser search for men sexual abuse group in Arkansas.
Their affiliate nearest Russellville is located in Clarksville. http://ozarkrapecrisis.com/
If they're not the end of the search they are a good place to begin.
I have taken to the stand-up comedy stage to educate other male survivors and those who try to love them. I blog about my isolated religious upbringing where physical and sexual abuse were commonplace and I serve as a facilitator of a weekly support group for men who have suffered sexual assault.
