I like your outlook. It's alright to have boundaries. We had our boundaries shattered, and it certainly takes time to learn them. I happen to think that you are strong for doing inner work, the kind of work that a "normal" male doesn't have to do. Normal is such a relative word, we hear it all the time, but really it doesn't mean anything. You are normal for having been sexually abused. I think it's a positive step in the right direction to have discovered how your co-worker's behavior affects you. With this knowledge you can reflect on a constructive response and assert your boundaries confidently. Heal well brother.
