boyfriend with a small penis

Mariletty
Okay so I looovvee my boyfriend with all my heart, he is perfect in every single way...except he has a small penis. And I mean, micropenis. He's probably equivalent to a chunkier baby carrot. We haven't had penetrative sex yet but I'm wondering if anyone who has experience with less well endowed men had any advice? 
Please. I am usually the one people look to for sexual advice but this is the first small dick I've had to work with, I'm out of my element and I just want to make sure that when we get there it's not embarrassing on either end. Any positions that work?
