Mansure 

A term describing a man's sexual aura. Men with high levels of mansurity are sure of themselves and extremely confident. Any men with intense sexual pheromones would exude mansure or mansurity.

(Ex 1) With such mansure, I am always confident at parties.
(Ex 2) I have a high level of mansurity and it shows.
