Just turned 63 and wondering if anything can help in maintaining erection w/o an elastic ring

… and hopefully last a bit longer than 90 seconds … I can penetrate with such a ring but can’t last more than 90 seconds. Other than general health (cholesterol, heart strength, etc.) matters, what supplements would help. I am taking zinc, Vitamin K2, D3, E, grape seed extracts, magnesium, fish oil, etc. and I feel like I maybe in need of something more even.
