May I also add,

Traditional condoms may subtly squeeze the blood out of your erection. Similar to squeezing the toothpaste out of a tube. Also avoid positions like cowgirl where gravity works against you. Try only the ones where the heart is above your cock. Doggie, Mish, standing doggie, lazy dog. On other words the male dominant positions.  

As for the over the counter supplements. I have experienced mixed results. After much research I discovered that some actually worked because they actually had the same  active ingredients that Viagra and Cialis had but managed to go under the radar due to their "Suppelmental" labeling. Many have been pulled from the shelves, just to return later without the prescription grade active ingredient. In many cases a placebo effect did take place and guys swear by them. However, when a new subject tries them, the results tend to be less than expected.  

If you are middle aged or over, overweight, have high triglycerides, high cholesterol, are diabetic, have low testosterone, have high blood pressure, have a stressful home life or career, are depressed, or use recreational drugs. All of the above can and do contribute to ED.  

There is no way to circumvent the issue. These magical ererction pills that the gas stations sell amount to little more than snake-oil. Do yourself a favor and make an appointment with your physician or hire a personal trainer and nutritionist then work on your cardio and do lots of squats and plyometrics.  

PM me if you have any questions.

Good luck and we are all behind you,

Same here with exercise and protein. Don't forget get rest and high fiber diet.  Very important when you are consuming a lot of protein.
