I've never been in this situation but I would want my gf to tell me as soon as she felt comfortable to share that with me. I would then ltake it slow and let her drive the physical relationship at a pace she was comfortable with. I will say this tho, when you do say something, if he reacts angrily, give him time. In that situation i'd be angry that you had to go thru that, not angry with you, but with the evil *stards that had done it. I may need some time to process it and calm down.
