Boyfriend is shy to get naked

I'm 24 and my boyfriend is 22. We've both decided to lose our virginity to each other and spent many occasions being completely naked around each other before we finally decide to do the deed. However, surprisingly, my boyfriend seems to be a little shy when revealing his penis to me. He blushes a lot and asks me what I think and whether I like it. I actually don't get shy being naked around him as I'm a lot more comfortable but he keeps feeling shy, especially when his penis is erect and fully naked. Has anyone else found this with their guy? I actually find it rather cute as it makes me feel I'm seeing such an intimate part of his body in such an aroused state that no one else will ever see it. That turns me on.
