Recently, I had someone over and was about to get it on, but then I couldn't. This has never happened before, and I can get it up in other situations but it's not as firm as normal.I reckon I may have a zinc deficiency, has anyone had any experience with this?
Could be psychological.
Would zinc help?
Goddamn, more likely than you think
OP here, I had a fine one today but that was solo.What the hell?
