if it was two weeks ago, by now you will be able to wash the wound fully and then let it air dry for around twenty minutes afterwards. no harm will come to the wound, and it will be a damn sight cleaner after! it will have healed almost entirely, otherwise the stitches would not be removed. you can also reduce the size of the dressing to fit the wound (i find that nurses in general hospitals always put ridiculously-sized dressings on wounds that are totally unnecessary - i'm a psych nurse, btw, and think less is definitely more when it comes to bandages etc.). this will make things easier for you all round. be brave and bold!
