How can I (23F) make my new boyfriend (24M) feel comfortable with my male friends?

Hello!

I (23F) met a guy (24M) on vacation and we have been officially dating for about 2 weeks now. He lives in a different country than me and I only just got back home yesterday. One of the first things I did was hang out with some of my friends (all male) since they offered to pick me up from the airport.

I have a lot of male friends mostly as a result of my degree and hobbies being male dominated. I did tell my boyfriend about this fact when I first met him. My boyfriend seems to be a little insecure about this and says that he trusts me but not necessarily the intentions of all my friends. He has been cheated on in the past and I guess that contributes to these feelings. He was pretty open with telling me about how he felt a little uncomfortable with this group after they picked me up from the airport (he told me after this happened).

Is there anything I can do at all to make him feel more comfortable, especially considering that we are long distance and he can’t actually meet these people? Him being uncomfortable makes me feel really sad and I would be happy to do pretty much anything short of cutting all my friends off if it made him feel better. Any advice is appreciated!!
