but not just any gal can give a good one.

 
Massage gals tend to be best as they do them all day long.

two hours, sometimes the second pop has to be a HJ/BJ combination to finish on time.  I agree that age plus time zone changes can wreck havoc on sexual performance.  I do business in London several times a year, but I gave up trying to have a session during the free time I usually have on the day of arrival.  It takes me about 48 hours before I can fully enjoy a session, so I don't even try anything earlier the last several years.  

 
Some of the Kgirls I have dated on the outside have told me that many older customers cannot maintain wood long enough to sustain penetration until climax, so the finish is often a handjob.  I think this is a universal truth known by all of them, and if they just transition at the right time without making a big deal about losing penetration, nothing about it is embarrassing or awkward and they will get repeats from these older guys, who leave happy, and isn't that what it's all about.  

I would say necessary, not really wanted!
