Who IS "The Masked Model"?!

 "The Sexcapades of the Erotic Masked Model" is an anthology series  loosely based on my performing title. In the series, Gregory Hanes is the international male model and pornstar, known as "The Masked Model"  (sometimes also called "The Masked Twink"), but he also  moonlights as private eye and occasionally works as a spy for a secret quasi-government agency referred to only as "The Sector". Often using his modeling/porn gigs as a cover, Gregory travels around the world  solving mysteries and fighting crime all while sexing up random strangers and generally getting himself into a serious ass-load of trouble.

And since no superhero comic would be complete without some abnormal power or ability which makes the hero above average, the Masked Model also possess a special power which he is himself is ultimately ignorant of,  though it is occasionally alluded to by some of his more otherworldly foes. For reasons yet to be explained, the Masked Model's testicles  produce an unearthly enzyme which supercharges his semen and enriches his physical body. The exact nature of this enzyme is ambiguous, but it seems to gift Gregory with an accelerated healing factor, decelerated aging, and his semen can be used to create a powerful elixir when combined with the proper ingredients...so basically he's toting the  Philosopher's Stone around inside of his ball-sack.

With this strange power, the Masked Model is nigh-immortal as he can heal from virtually any wound no matter how fatal. Therefore the only true way for his enemies to successfully kill him is to cut off his balls before delivering the killing blow. Incidentally, the enzyme from his testicles could also grant Gregory superhuman strength, speed, and hyper-intelligence, but only when a copious abundance remains in his  system for a prolonged period of time. Simply put, Greg can become  Superman so long as he never orgasms...unfortunately for him the enzyme  also sends his sex drive into high gear turning him into a promiscuous horndog; which is probably for the better, as the more of the enzyme that remains in his body the more horny he will become until he finally devolves into a sex-crazed rabid madman...with superhuman strength and speed.
