You can be addicted to anything. I think it would be very easy to be addicted to sex.. climax anyways..
Yeah it definitely exists. I'd say I have a ( too?)high sex drive.But I can't see how thats the same as being addicted to sex? Western society has a strange attitude to sex.Its obsessed with it , but its uncomfortable with it.Whereas other cultures treat it as a fundamental energy in the universe. But I think there can be something pretty sad about someone being a slave to their sexuality.(Unless maybe , say its their job or whatever...)
