If GK's were male privates, you have invested in a 6 inch long and 3 inch thick member. While not something exceptionally impressive, it gets the job done and not many targets will complain. But for the true beasts out there, you will be requiring 9'' minimum (Masa). The problem is, those beasts will likely spill their koodies on you because they have a thing for getting battered by big bad *** GKs. No one wants them, they smell bad. Enjoy your 6 inches, friend of OP. It gets the job done, and when it doesn't, you shouldn't have tried anyways.
Edit: note to self, don't post on these forums high, jet lagged AND under the effects of sleeping pills due to more than 24 hours of no sleep.
