Starting to affect my New Year’s resolutions…

If anyone can give me a tip please do before all the best of this year runs down my feckin leg... I've literally read everything on boofing coke, tried every different syringe, varying amounts of water from 0.5ml to 5ml, every position known to man or woman, inserting from 0.5cm to 2inches and yet can't stop the white power from leaking I'm not saying all of it but starting to really piss me off… Anyone managed to find a way of sealing the deal?? I will be amazed if someone came up with something I’ve not already read but giving it a shot.. Life long friends for a winning solution 💫
