Beyond the urinary tract infection or the yeast infection which will screw EVERYTHING up for your er... log Gamel, you are just experiencing a SIZE incompatibility. She must be geneticly able to dilate to a certain degree to take your girth, unless your head is brushing up against something kinda hard and strange (I don't give a shit what the doctors call it, it is the end!), it is microtrauma from your girth.

Good thing you are uncut, or you might be experiencing microtrauma as well. But if everything clears up from doing what BronxBombshell said in her post (she is VERY knowledgable, having a lover who was 10 inches in the past), you have nothing to worry about and can fire away. Let me just say that your hands and fingernails have WAY more bacteria than your cock could ever have. Was them BEFORE and AFTER you pee and keep your nails trim. Wash your hands BEFORE you have sex, her cootchie will thank you for it. You might want to beat off before you have sex, it will reduce your size a smidge which wouldn't hurt that monstrosity of yours at all.
