Sorry kid. There’s no going back. Once the party’s over, its over.
I mean in a Freudian sense you spend at least some portion of your adult life trying get back to that point… but really its all simulacrum.
Its even worse when you yourself have your own kids and you’re suddenly smacked about the face with the reality of mammary glands and their (purely) utilitarian function as a source of nutrition for the progeny you helped create. (for me anyways) Procreation meant getting dealt a massive hand of creep factor and I suddenly felt a lot less inclined to put mouth to nipple. I feel like something has shifted now (in my brain) and that, that particular life goal has been irrevocably taken off the menu.
