Yes, that would be the other option. Or, I suppose, you could make it like a tumescent phallus; this would be an aid to potential quitters who might, after a while, find it tiresome sucking on a jap's eye.
What about the gays and the ladies, though? They may greatly enjoy sucking on a huge, artificial Johnson.
Frankly, I can't believe you've been so non-inclusive of sexual minorities like homos and birds.
