got my helix and medicine bulb tube dropper

following read forum instructions i bought this thing to put some lube internally..i previously got one of those meat injector syrenges...too big...threw it away...ok..this has markings on it like 1/4 teaspoon..1/2 teaspoon..ect..ect...how much is the needed amount?

before with the "big injector" i put about an inch worth of ky jelly in it..inserted and pushed the plunger...worked good with my progasm...only problem was when session was done and i pulled the progasm out..a flood of lube came too...smart enough to have a towel under me or i'd have fucked up my bed's sheets...think this was too much..duh..lol...

am going to try my new helix this morning before going to bed ...but haven't seen any recomendations as to how much lube to insert internally as in amounts..fill it up?...half-way full?

am excited about getting this helix..gawd i've bought 2 aneros models in 3 weeks...hope it is a different sensation than my snug fitting progasm...shouldn't it move more freely?
i hope so...am loving this journey in sexual experiences i've never been to with regulal marital sex...

any answer appreciated or we'll just wing it and go..lol...

later..zombie
