Actually before I started punting, I tried a few hook up sites. Most just wanted you to spend money at say 50p per email (soon mounts up) or buying online content. The ones that actually were trying to provide hookups require wining, dining etc and would be impossible for any man wishing to keep his carnal exploits secret.
On reflection punting may be expensive, but it provides a quick release with no commitment before or after. Plus, depending on how often you punt and how long the meeting, you are in complete control of your finances.
Just a point of view I confess
