What should I do to heal from the trauma of sexual violence?

I'm sorry that happened to you. It must have been very unpleasant. Thank you for sharing your feelings with me.

I wonder if your brother is sexually harassing you now. That's what I'm really worried about.

So you feel uncomfortable when someone you like gives you a sexual vibe. You get scared. It's one thing to like someone, it's another to accept what they do.

My advice is to express yourself to your partner "I like you, but I don't want to have sexual activity yet" to build a relationship. 

It is possible to be sexually violated at a very young age by someone who has more power and position than you. 

Usually, people who are harassed know that the other person is too young to know what is done to them. 

So, you are not responsible for the damage that has been done.

It is not abnormal to feel aversion to sexual things due to the effects of that damage, but it is a normal reaction of the mind.

First of all, you need to talk about the experience with someone you feel comfortable with.

However, you do not have to force yourself to talk about the experience. Talk about it at your own time, with someone you feel safe with.

I believe that you can recover from trauma slowly but surely.
