Intimacy without sex

My boyfriend is kind of scared if sex right now.... He was raped by his friend at his friends bachelor party. He basically wanted to drug and rape my boyfriend before he got married... My boyfriend cut off his long hair because of how Scott(his friend who raped him) used to pull on it and joke about him being his bitch and how feminine he looked. I ended up shaving it into a neat military haircut so when it all grows back it will be healthy strong hair that only we have touched. He's really struggling. Especially since he decided to tell Scott's wife and she called him a liar and that my boyfriend is just in love with her husband. My boyfriend is bi, but someone being bisexual isn't a free pass to rape someone. His friends pretty much covered for Scott except his female friend. She left because they left her at a club all alone and she got mad and went home... She has no idea what happened. Honestly Scott has sexualized her before too so I'm scared to think what would have happened if she didn't leave. But my boyfriend obviously can't do sex rn. He says no matter how hard he showers he feels dirty and too dirty and disgusting for me which I said isn't true. But I'm not pressuring sex. Any ideas how to be intimate without having sex?

He did not go to the police.... It was hard enough to convince him to tell his wife but we do have his clothes from the night buried inside his closet if he changes his mind
