Hi Sorry you had to go through such a terrible experience. Rape is such a terrible crime that leaves so many issues behind that the victim has to deal with later. There are quite a few people here who may be able to help you with that. I hope so.
About your friend... not sure how much to say about him. That was incredibly insensitive. We all say insensitive and inappropriate things at times but after you explained it he should have understood. A lot of us are "sex-oriented" so that's not a good excuse. Maybe think about finding a new friend or just tell him the subject is closed?
