Hah! Being a a total sex addict I've always tried to keep a step ahead knowing that at some point things start to point downwards. Pun intended.
I actually was standing at the pharmacists counter in Buffalo the day that viagra went on market with a prescription from Canada (as it wasn't available on Canada yet)
I always looked into performance enhancing concoctions and drugs. Lol
Used to get wasted on GHB, pop a viagra and smoke some pot. The sex was insane.
There are herbal remedies available from Chinese shops including ginseng, horny goat weed and a few others. I've used yohimbe which is a bark from an African tree but that shit makes you sick big time. Stay away!
Cialis does squat for me but viagra is foolproof for me but more than 3 times a week and it can run you down. Healrh risks for those with heart problems.
The best herbal remedy I've found is tribulus terrestrius
https://en.m.wikipedia.org/wiki/Tribulus_terrestrischi
which is a thorn from a plant that you boil into a tea. The taste is strong but earthy and actually is pleasant to me. A bit every morning and after a week or so its amazing how the big guy will wake you up. Lol. Don't remember how it actually works but I think it helps promote testosterone production.
Traditional Chinese Medicine Edit
In traditional Chinese medicine Tribulus terrestris is known under the name bai ji li (白蒺藜). Tribulus terrestris known as ci ji li (刺蒺藜).[16] "Confusion with Astragali complanati Semen (sha yuan zi) originally known as white ji li (白蒺藜 bai ji li), led some writers to attribute tonifying properties to this herb ..." (from the wiki link) it doesn't seem to have any I'll effects either.
You can get it online also in tablet form if you can't get the actual thorns to boil up yourself.
My two cents.
Happy ahhhh, well you know.
