Had a lap dance with my...

Had a lap dance with my ATF, beautiful, friendly girl with great body. It was a 2 for 1 dance for $25. The one way contact was "good". Unfortunately, I was 'finished' before even the 1st dance was over. The girl asked what's going on. I said 'I was too quick'. She declined to dance further. I said 'I am sorry and paid for the dance (s)' and left the club.

How do others prolong the enjoyment without being so quick? Any protective clothing available to hide the embarassment - if it cannot be controlled?
