Pretty simple: Is TOO much caffeine (over 200mg) going to effect stimulation, performance, erection longevity, and/or potential further of erect penis size as time goes on (caffeine has been rumored to stunt growth in the body; so why not the dick as well?) Just curious.
Stimulants have a tendency to inhibit ability to have decent erections. That is why medications like Ritalin, Adderall, and even high caffeine amounts all cause a decrease in sexual function. They create flight/fight type reactions.
Don't believe any correlation exists through my experience. I've consumed massive amounts of caffeine over the years, and rarely experience erection problems. Guess I will never know if I stunted my penis growth ... ... ...
I've been drinking strong filter coffee all my life,it's never caused me any problems.It doesn't keep me awake either so I don't believe any of the stories about caffeine.
Caffeine is vasodilatory. Simply put...it opens your blood vessels. This is why coffee is sometimes used as a quick fix during asthmatic reactions (helps open lung passages). I personally have an erection after indulging on caffeine. It's like clockwork for me. In other words, caffeine HELPS your cock.
Caffeine makes me horny. I often drink coffee or black tea before watching porn to enhance the experience. Well...scratch that...I probably feel compelled to watch porn because of the enhanced libido brought about by the caffeine. It really sucks when it happens at work though.
