What do you call it when you don't like any gender but you like all kind of sex?

I would say that's called being bisexual.

that means you are bisexual.

In the strictest definition, you are NOT bisexual. But with raging hormones, you are over sexed. There is an old term for it: 'Any port in a storm." Caught the drift?
You too, should be cautious of STD's.
