Guys: When (or if) do you ever lose interest in sucking a GH cock?

Guys: Is there a point that you give up or your interest wanes when sucking a GH cock if he hasn't cum yet? As for myself if a guy hasn't cum or acted like he isn't even close in roughly about 10 minutes or so, I tend to give up and move on to the next potential cocksucking adventure.

Believe me this doesn't happen hardly to me since the vast majority of GH cocks seem to cum within a 2 to 10 minute timeframe.

Are you one of those guys who keeps sucking a GH cock no matter how long it takes to make him cum?

Do you also move on if a guy can't keep it up, or do you keep trying to overcome the situation by not giving up?

Lastly, in your experience, how long does the average GH cock last before they cum?
