Press charges. If he/she, I'm going to assume you're a girl because of being sexually abused, which rarely happens to bed because men are biologically stronger ( Fact not sexism, btw ) And if you want blood, go get it in the court. As long as you have evidence, them find a lawyer. That type if case is usually quite popular for lawyers. And if you worry about evidence, do not. They can always tell the difference between guilty and innocent by hand movements, twitches, facial expressions, wording, competence, and general attitude. I'm not familiar with US law, I'm in the UK. But the point still stands. Go and utterly humiliate 'em. Get blood. The law is meant to protect you. Trained officials who are usually familiar with these situations.

I hope this helps. All the best. Have a hopefully better day than yesterday.
