early 60's and no problem getting hard during foreplay-but as soon as the condom goes on i start to lose it
any suggestions

Seek out providers who are female condom friendly!!!
 

as one of my regulars would say.." dont think..just fuck "..over thinking any situation takes the thrill away..

Often if the provider is hot enough, she can make up for the reduced sensation by aggressive BJ or manual stimulation along with lots of vocal encouragement.

Otherwise, I find non-intercourse methods of getting off like BBBJTC and/or COF, Russian, etc.  Some gals are even great at hand jobs.

The FC solution is also good, but there are a very limited number of providers who use same so far.

isnt my exact type that turns me on the most. Stick to the ones that suit you the best. Or you can try the lowest dose of Viagra. That worked for me too.

i am in excellent shape -play sports-bike -hike etc-and look very much younger than my age except in one place

I am highly skilled this is an Art!

Different brands and sizes.  
You might find one that works better for you.

I prefer Crown skinless. Check the link for assorted packs. Be aware, some providers prefer using their own, and don't like it, if whatever you bring, isn't in the manufacturer's original box. However, if you've got a fav that you see regularly, she may not have a problem.
