You are a very fortunate man. So much energy, time, resources is lost on pursuing the quest to drink the last drop of sexual adventure, and in the end it always disappoints. It is counterproductive actually, because the more you partake in sexual perversion the less you appreciate normal sex. I wish I had grown up normal like you. Sadly, I found my father's porn collection and thus began a 30 year descent into sexual depravity the likes of which would make the Marquis blush. Porn has a lot to do with it. It's true, the more you look at one kind, the more your brain needs an additional hit to activate those pleasure zones, it gets more and more extreme. So, yes, you do get extra pleasure from it, for sure, but there is a large price to pay.
