I had a session with a beautiful women yesterday I had never met before.   Although I was in a very horny mood I was not able to "get there".  So close to climax but no luck.   She made her best effort and I would see her again.
I am a 69 yo male with no particular physical problems except HP meds.
This is the second time it has happened in maybe a dozen sessions with various ladies over the last few years.  Yes, I was tired and excited preceding the session with anticipation.  
Any suggestions for this old man would be appreciated.   Special diet the day before?   Over the counter drug?  I have no problem getting it up at all.

Dang.  To be young again.

and try getting some potassium either through bananas or avocados.  

 
And of course, plenty of rest.

You will find a lot of info there about many of us in the same situation --and I'm 64 million years old (reference the handle).

I'm on a blood pressure (BP) med that makes it difficult to reach an orgasm at times -- if I'm not fully rested, not as much hydration as I should, etc. I find if I skip the BP medicine the night before and the morning of our session, I'm able to "cross the finish line" with no problem. If it's a 90 minute to 2 hour session, I can go for two with the right provider.

I also find that if I'm concentrating so much on "the prize," then it's more difficult to reach that prize (the oft times elusive orgasm). Relax, enjoy and don't put too much pressure on yourself -- concentrate on having fun, pleasing each other and good things will happen.

I'm on benazepril HCTZ.  I would consider taking your advice and laying off the drug for 24 hours before a session.  

Thank you!!

All bp meds caused sexual dysfunction to some degree. Even  providers have told me this. See your doctor, ajustments in meds sometimes work, and the ED drugs should work unless you got real serious issues. Delayed ejaculation from porn will do it also. If are you getting a full erection its either the drugs or psychological. So there's a cure for you.

Thanks to all for your replies.  I have been on BP for years.  I have no problem getting it up.  But my recent session was a disappointment because I couldn’t cum.    
I am not sure how hydration would help but will try lots of non alcoholic drinks next time and maybe skip BP meds.
She did her best but I couldn’t get there.
