We were taught pleasure as a curve you have to complete. No climax, no success. That looks more like a metrics dashboard than a body, and it has probably worn you out in more than one bed.
When tantra is not posing for a photograph, it offers something far less heroic: staying with what is here. Heat in the belly. Honest boredom. An orgasm that arrives and that nobody applauds. Taking the goal out of pleasure does not make it lukewarm, it makes it yours.
