賢者タイム : 欲求が満たされ、それまでの熱狂的な興奮が冷め、脱力し、冷静になり、自分はどうしてあれほど激しく興奮していたのかと省察するにいたる状態などを指す表現。男性が射精して果てた直後の心理状態を指す場合が多い。

Sage time (Wise man's time) : After a desire being fulfilled and the feverish excitement fading away, one feels so drained and be rational that he gets to reflect and meditate (省察する) on how such fierce excitement/desire arouse to him. Usually used to refer to men's psychological state right after ejaculation. (Source: Weblio)
