The biological purpose of sex is procreation, where male and female genes merge to produce offspring. The pleasure of sex, is like a carrot on the string, that helps lead people to this end goal.
Picture a horse and buggy, with the buggy full of fresh produce. I need to get this to market, but my horse does not want to walk to the market, today. Selling the produce is my goal, not a horse walk. However, I need the horse to walk to get to the market. To help the horse satisfy my goal, I take a carrot on a string, and place it just in front of the horse's nose. The horse walks, not so much to go to the market, but to get the carrot.
As the horse tries to get the carrot, the horse is distracted and he unknowingly pulls the cart to the market, against his original judgement. This is how sex works and why many people start with no intention to have a child, but end up with the need for abortion. They were chasing a carrot on the string, with no intention of going to market, but they still end there. The unconsciousness induced by the carrot, acts as a distraction so the original resistance, is made less conscious.
The brain has a way to reach an end game, using distractions. Consider a drug or alcohol addiction. The next day, the person feels like crap due to their hangover.
The hangover is not really the goal, even though this is the end of the journey. The hangover is a conscious side affect of achieving a final state of brain chemistry. This end level of brain chemistry, is the original goal and sets the original potential. We are conscious of its steady state, by the hangover. Sex with a stranger can be exciting when engaged, but very awkward when done. Once the carrot is eaten and you realize you are at the market, there is some buyers remorse.
The vision of the addict, is not the final state of hangover, but the shorter term vision of the carrot on the string called euphoria. Euphoria is an energetic transitional chemical state, that is needed to generate the activation energy, needed for the final state, which is driving the entire process. The carrot on the string is the most conscious aspect of the entire chemical train. This main awareness of the transitional chemical environment, can fool people into thinking this is the goal.
A sex strike would be where we need to go to market; same biological urge, but have to stop using carrots to lead the horse. However, since the end goal is going to market; offspring, and not just a horse walk, the brain will find an alternate lure to make the horse walk, since the end goal is wired into the brain.
This alternative lure may not be what anyone expects. Picture a drug addict, who runs out of his favorite drug. The chemical end game still runs in the background, so alternate chemical paths will be attempted, until a new lure gets the horse to walk to market. Instead of a carrot, a stronger lure like sugar, may be needed, and will cause a more compulsive walk and regret.
