The safety of condoms can cause extreme action in the quest for excitement? Perhaps our world is too safe for our plastic brains. Might novel porn have been nudged along by the condom?
I'm not advocating against safe sex. The idea of lower risk, be it from STDs or pregnancy, is what condom represents here. It also could represent the idea of lower risk touch just as one might be more willing to touch certain things with a glove than without.

Personally, I think that a balanced brain seeks a balance of stimulation.

What happens to understimulated brains? Atrophy or something else? Perhaps one day the sweet spot will be better defined. Though then we might miss the fun of figuring ourselves out.
