What is bhramcharya or 3rd percept?

Is it only pertaining to "no adultery" for layman or as "no sex" for monk? If such is the case, why in ganika sutta it was mentioned as "path middle to celibacy and adultery" for ganika(female dancers)? Conclusion:: 3rd percept varies from person to person. It is different for one who has the capacity to "no sex", one having capacity to "no adultery", one who has the capacity to "no sensual pleasures", one who has no-capacity or livelihood depends on adultery-- so "middle to adultery and no-sex(celibacy)",......... It's main purpose is to enforce people of various livelihoods, various traditions, various spiritual-levels, various situations(incidents) to realize the **cravings associated** with "harmone-loss through privates, mental-exhaustance in sensual-pleasings, breaking-percepts, various-perceptions, sankharas, ignorance". Is above conclusion true? Yes/No then justify? *(wholesomeness has essence and craving of never-dying.)*
