Deep clean quick!
I am really into BBC and group action.  If the foxhole is not squeaky clean then, the bottom is shamed!  The best approach is to lube the tip and insert slowly with very low pressure in the bathtub.  Then just expel while tube is still in and push it a little higher.  twist it around so it get all sides.  Keep doing til water runs clear and u got a good amount of the tube up in you.  Works way better than Cleanstream silicone nozzle!
