It's funny someone should bring this up because I have a similar issue when it's the "wrong girl". I've discovered recently that most hookers are completely incapable of getting me to orgasm, not just because I'm too cheap to double the session time, but also because I don't have the right feelings for them. On the other hand, with my ex, I last maybe a minute inside in the majority of cases.

Not that it wasn't a bad time though...

Previously I'd thought that only women had this kind of issue so it was a real eye opener for me. And I have the divorce to thank for giving me the opportunity to discover this. ;-D
