Hi Azapa,
Snorkel should really be out once you dive I often forget this but always try to remember it as it should not be in on resurfacing.There should not be much pressure on your lips sounds like something is wrong if you are having this problem. The guuhhh sound does,t happen to me but may well happen if the soft palate is not in the correct position which may account for the pressure on the lips also.
