Is Erotiphobia Like an Eating Disorder?

I’ve noticed in various subreddits that when the topic of sex comes up, there’s an outpouring of erotiphobic and antisexual sentiment that is quite vociferous.

Sex is a basic biological function like eating and sleeping, yet many people fear and revile it for some reason. While having sex isn’t necessary for survival, it is nevertheless natural and biologically rooted.

Thus I ask the following questions:

Are these negative attitudes toward sex pathological, analogous to an eating disorder like bulimia or anorexia? What accounts for them?

I’m a sex-positive male and I find them strange and off-putting, like someone saying they don’t like food or hate breathing. Any thoughts?
