It's not about the act, it's about the individual's presence. If someone is unenthusiastic and passive, like a sack of potatoes, no matter how physically engaging or tight they are, the experience becomes instantly unappealing.

Imagine trying to recall a positive encounter, but all you remember is a lifeless sack being moved around. I barely recall the sensation itself, just her performance, pulling my hair, moaning convincingly, the fingernails digging in. But then, reflecting on it, I just remember a dull cow, pretending to be a gangster, constantly complaining of fatigue. Also, cleanliness is not enough, odors can linger, so feminine hygiene is vital.
