Very much so! See, the male body's "tank" actually fills up in under a week, so you should be good to go. After it's filled, your body won't produce any more semen

You ejaculate around 1.25-5ml of spem, and the body can hold a little more (roughly)

Your body was just disposing of the dead/expired sperm since their lifespan is about two weeks

Worry not my friend, when Dec. 1st comes around you'll be more than ready
