What makes you think sexual fantasizing is normal?

I agree that it's harmful but that doesn't mean it's abnormal. People have been doing it since there were people. Having a sex drive is completely natural. Fantasizing is just a form of this sex drive. When used right it can be fine but we have an addiction so we should try to control our thoughts. Especially when porn has hijacked your natural attraction patterns and you have a weird fetish. Fantasizing at that point is somewhat strange and won't lead to a healthy sex life.

 

There you go.
