I can’t stay hard so I’m going to try a cock ring. Any suggestions from those who have gone before me would be greatly appreciated.

I've used them.  Get the one with the little vibe built in, have had good comments on that.

There are so many types and varieties of them now. Even a review of a certain one might not work for you...we are all different. What I did was buy a variety of different ones to what works best,

I like to mix them in with my fruit loops in the morning

I know this is going to sound ridiculous but pick up those boner bears that they have at sex world. They're like gummies and they work wonders I'm actually shocked at how well they work so are all my friends who have taken them. They're much different from Viagra and Cialis so I've been told and they take about 2 to 3 hours to actually kick in but once they do they are amazing. They definitely definitely work.

Dang LT, I just spit up my drink on the boner bears comments.
Hell I'll give em a try just cuz the name cracks me up.
I could get addicted to something like that!
Thanks for the info LT !

Go see a Urologist who specialize in ED. Ask about Penile Self Injection, first introduced in 1983. It is safe and effective. You should not mix Viagra and Cialis together, it can be dangerous.  A cock ring won't make you hard, it numbs and delays finishing too soon. Delay sprays work (KY Duration) with 7% Benzocaine to desensitize. Use a condom with the delay spray or you may numb your and her private areas and tongues. Always ask her first. There are also some SSRI's (Anti-depressants) that can be effective when combined with Viagra or Cialis or the Injection.

I second this idea, it's amazing

I am not giving medical advice; however you could try going to peptide sciences .com, order peptide PT-141 in injectable form, order a vial of bariostatic water, mix the two according to the instructions, by some alcohol swabs, and insulin needles, use 10-15iu’s injected into subcutaneous fat about 1-2” away from your belly button. Within 30-1hr you will be able to get rock hard.  When women take it they turn in sexual tyrannosaurs. Amazing stuff without the side effects.
