I'm a 50 year old male.. and suffered from poor performance (Typically like most men.. To counter act that I used ED meds and supplements to increase semen quantity etc). in my late thirties til last Dec. That's when I stopped drinking all together! Once I stopped drinking my wife and I noticed over time I didn't need the meds to get hard and stay hard. So now after a solid six months. I fuck her like i'm 20. The other day I went for 40 mins. It's crazy. I stopped drinking because I went from being a fun drunk to later in life being an asshole.drunk The benefit I've received is morning wood, and longevity while fucking!. If she wants to ride it for hours I'll take a pill. I still take the Testosterone supplements (read up on the benefits) and semen producing pills (she loves buckets of cum) but I don't need the pill to get hard and stay hard. Take that as one sample of a benefit. Side note.. penis hardness is matter of pressure. Energy drinks help!!
