One of the biggest strengths AND weakness of men is that they think LINEARLY. They always think stuff as ABC or step 1,2,3 and then FINISH.
That is understandable, because most men use LOGIC to operate in the world and naturally think things happen in a step-by-step manner.
But when it comes to attraction/sex/women, logic is the ultimate enemy because love & relationships are all about EMOTIONS.
So sex is not about hugging -> kiss -> tongue -> oral -> penetrate -> finish with man’s orgasm!
But real sex is cyclical／週期性, it is filled with CHAOS and UNCERTAINTIES.
Sometimes you start with oral, sometimes she cums a few times before you, sometimes there are multiple bangs,
but there is NO GUARANTEE that the same thing happens in the next time.
If you want to have great sex, stop aiming for certain goals like orgasms, enjoy being in the moment and FVCK however it feels right.
When you discard the formality, you two will have less stress, and sex will be a lot more pleasurable!
