I'm worried my boyfriend is the jealous and insecure type?

I'm in a worse situation that you are right now. I'll answer this one if you can answer mine alright? If you are comfortable answering his question, just be honest. Tell him theres nothing to worry about bc you were single before you began talking to him. If u can maybe show him ur pictures on fb as a proof that you have nothing to hide. I hope it works out with you two.
