Why does my boyfriend talk to other girls?

Canadian21
He's been my best friend for 5 years and we recently decided to get together, and I thought everything was great, we both have security issues, and he went through my phone so I thought it was only fair I went through his, I found that he sent a picture of His manly parts to other girls. I however had nothing to hide. He talks to at least 3 other girls when I'm not around, and now hides his phone, when I ask who he's talking to he says its someone else when its not. I'm just so confused on what to do?
