Eating out...

ally
My boyfriend has only eaten me out a few times, and it has only lasted at least a few minutes. I think he might be bored? But I love it! 
And not only that makes me feel self conscious...but I feel the need to always shave for him if he is going to. ( although he says he doesn't mind me not shaving) but whenever I do shave I get red spots and I block him from going down on me.
 What should I do? I wanna feel more comfortable around him doing it
