Concerned about my man

My man and I have been dating for a solid 6 months. I feel like I trust him 100%. I just have 1 mild concern. The majority of his friends are girls. And I knew that going into this relationship. Which is fine, whatever. Well the other day we were in the living room watching TV. He was on his phone so I looked over to see what he was doing. I saw that he sent a friend a message about a dildo after she stated that she needed an emotional companion. I'm sure he was just joking with her but not 100% sure what's going on there. Well a little while later he's on his phone again. On the instagram I see that he posted on some chicks photo something about just having the balls to say that she was gorgeous. I don't think he's once ever told me that. Ugh I just don't know if I should legitimately be concern d about this. Any help/advice is greatly appreciated!
