There is nothing wrong with you, you are not to blame for what happened; you can either embrace who you are and acknowledge your preferences regarding sex, as long as they don't harm you; or you can choose to work on aspects you wish to change, always with the help of a professional or trustworthy information.
It's important to acknowledge the seriousness of your experience, be kind to yourself and understand that letting go is necessary for growth, clinging to it will only hinder your progress. It may be tough, but it is within your reach, trust me on this.
