At what stage of the relationship should a guy?

At what stage of the relationship should a guy tell a girl about his small dick? And how would you as a girl feel / react to it?

Initially whenever they start talking openly and comfortably
Only before intimacy he should just warn that he is small so be prepared
No need to tell it. Just bare it in front of a girl and let it see for herself
Guy with small dick shouldn't even bother to date / be intimate with a girl
