How to deal with being an autistic girl with a mild intellectual disability and people thinking guys are going to take advantage of me?

I am high functioning autistic and have a mild intellectual disability as well and I am always shunned from hooking up because people think guys will take advantage of me. Why is this true? I can consent to sex but people will still think a guy would take advantage of me because of my disability when I try to have casual sex. That is why every guy blocked me when they found out or could tell about my disability. Why am I shunned for having casual sex because of my mild intellectual disability? I know what I’m getting into. Why in society they don’t want them having casual sex?

And also by mild intellectual disability it means my iq is around 75 with adaptive behavior problems what do you think of that and casual sex?
