how long does it take for male flowers to fully develope?

hey guy i wanted to find out how long does the male flowers take to open up?because i got this female turning a little hermie like the male pollen sacs are coming out of the calyx. so i wanted to find out how long before they fully develope.there about 1/8 of an inch sticking out of the calyx i just discovered it. the plant is 49 days into flower gonna harvest most of it but the male flower part.so yea what would your guess be.oh and its indoor cfl mini perpetual grow i dont want everything to be pollinated.i plan on using it on two differnt strains sativa dom and back to its self which is a indica dominant strain theres two pollen sacs sticking out of the calyx one for each that should work right.
