Petko,
Sorry to hear about your affliction. Happens to men your age more often than you'd think. Nothing to be ashamed of.
As for remedies: I've heard about one, indeed, but cannot vouch for its effectiveness, so follow these instructions at your own risk (which, as you shall soon see, is considerable).
"Track down a wolf in its prime and attack it with nothing but your bare hands. Pin it to the ground and strangle, repeating these words: sum vir. Once the deed is done, rip its heart out and eat it whole. This shall restore your manhood right away."
Again – can't tell if it's going to work. If I were you, I'd drop it. But by the tone of your letter I infer you might follow through with the above, in which case: good luck, old friend.
Vera
