I reallyythink you have a golden opportunity here. The fact that your boyfriend has been stumbling around your pussy like he needs a roadmap and a flashlight most likely has less to do with your geography than with his level of experience. The fact that he's so grateful for the pussy only proves my point.
Take this kid under your wing so to speak, show him what you like and what you don't teach him to be a good lover. If you want him to go down on you, make him go down on you and make him good at it. And if he comments on your pussy not looking like a porn or playboy pussy, educate him on that too.
Believe me, if you think he's grateful now...Haveng a lady show himmthe ropes is very likely to be a dream come true for him.
