Sex is like mushrooms

First, not those mushrooms, I'm talking about the food only.

Sex averse = mushrooms are gross, they taste like erasers!

Sex neutral = I don't have an opinion on mushrooms

Sex positive = Mushrooms taste good!

Demisexual = I don't usually like mushrooms, but if I find one I like, it's my favorite food

Not a great analogy, but as a grey sex-positive, it's like, "I never crave mushrooms, but whenever I eat them, I'm like, 'damn, those are good, I should eat those more often!'"
