We all know caffeine has its effects, I noticed some articles state that caffeine increases cortisol, oestrogen and SHBG!!. In perspective, would the rise of estrogen, cortisol and SHBG be the cause of stim-dick? or is stim-dick caused by vasoconstriction to peripheral parts of the body such as toes, fingers etc.


This could get interesting.. inb4 accused of stimulant addiction.
