My best guy friend saw me naked?

Anonymous
Last week I was at my best guy friend's house getting ready to go out for his birthday and I had to take a shower in his bathroom because I had just come from the gym, so I was a bit of a mess haha.

Yeah so 5 min after I turned off the shower I was moisturising and stuff and he just came walking in. I tried to laugh it off like "heeey man, chuck me a towel hahaa" but he just kind of stood there in shock or horror or something for like 10 seconds. Then he ran out?

So since then he's been damn awkward, he won't make eye contact or initiate conversation. I have tried to let him know that I'm not embarrassed and that I don't care, but he just mumbles -_-. I find this odd, I know he sleeps around a bit, so he must know what a naked girl looks like.

Just for context we're both 17, he's a dude and I'm a girl but we've known each other for 6 years now, are very close and he's never said anything to allude to some lifelong crush so I don't think that's what this is. On my profile there are pictures of my (clothed) figure, I guess the relevance of this depends on what you guys interpret as the situation, so you don't have to look at it if you don't think it's important.

So questions:

1. Why is he acting like this?

2. How do I make him stop acting like this?
