Rape often causes feelings of dirtiness, worthlessness, etc that other forms of powerlessness usually don't.
Many years ago, an ex girlfriend got back in touch, and wanted sex. Just once, it turned out. Then, I was diagnosed with Chlamydia and HSV. And later, I hear from mutual friends that she was bragging about infecting me.
Anyway, that I feel dirty about. Because I will have HSV for the rest of my life. Maybe that was rape, but in a devious way. And I get that forced risk of disease is part of the trauma about rape.
