What are the key determinants of the price of a gigolo?

For someone who has seen both sides of the coin, I can only say: it depends case to case. But on a general note, the following matters in order:

Like-able face and personality.

Good height.

Attitude. (most men fail here; most are too desperate)

Stamina.

Penis size and width. (Didn’t matter so much)

Knowledge about foreplay.

Knows how to turn on and playing with fingers.
