See Ladies that offer MSOG.
If you have trouble going a second round, try a hot compress to the balls directly after the first nut. A super hot wash cloth is part of my normal clean up routine anyway.
I have a regular client that is close to 65. On several occasions, using this method and without any medications, he has gotten 3 pops during a one hour session.
And BTW....like your Doctor or Lawyer, your Provider is one of the last people you should feel embarrassed with. This is what we do. Be honest and open and she should be patient and helpful.
