Is it normal that i want to show my body?

About 2 weeks ago my bf was talking to an online friend and somehow ended up talking about sharing pics of their girls. I was a little bothered by it but he convinced me since it wasn't such a bad thing and it would only be once. So I took 2 pics on his phone and gave it back. They talked about me for a while, my bf showed me some of the messages which had some dirty talk. I pretended to ignore those parts. A bit later he asked if he had any more pics of me, my bf asked me if I wanted to send more. I was really enjoying the "compliments" and figured that if I was liking the attention and my bf was fine with sending him pics of me then I shouldn't say no. But when I undressed in the restroom to take those pictures it felt different, I was enjoying it. They weren't just nudes, I was taking them FOR him on my bfs phone. The whole thing and how wrong it was turned me on more than it should've. I took the best pics I could and went to our room to hide how aroused I was
Later that night when I was alone in bed everything hit me all at once, and I found myself fantasizing about it. I realized what I really loved about it was showing off my body and having someone talk dirty about it
Since this happened the thought sometimes crosses my mind to post pics online. I haven't spoken to my bf about it because I'm afraid he'll be upset and I don't want him to know how turned on I was that day. Is it normal for me to want other guys to look at my naked body? Should I tell my bf or talk him into letting me post pics? Or am I just getting overly aroused by something that shouldn't be a big deal?
