Is it normal for my guy friend to change in front of me?
Ok, so a couple weeks back I had a pool party at my house, and I had a few friends over. Well, my best guy friend was the first to arrive. I had my bikini under my regular clothes, and I assumed he had a swimsuit under his, so we got changed in the same room. Except when he took off his clothes I saw he didn't have a swim suit on, and for a few seconds, he was completely naked, and I saw his penis.
I don't have any feelings for him, and I don't think he has any for me, but I feel awkward around him now. Whenever I'm around him, I can't put the thought that I saw his dick, out of my mind, and because of that, I've stopped hanging around him recently. But I don't want this awkwardness to break up our friendship. Is this normal, and what should I do?
