BF looking for new friends

Hi all,
I would appreciate your opinion. My boyfriend and I are together since last summer and live together since this June. We are both home officing and in our country is lockdown, which he takes worse than I do. So he decided to learn the language of the country where we live and started to talk to some native speaker girls via video calls. He doesnt have many friends here, actually only one male friend, and this is his way how to find new ones. I support him with learning (I also offered my help) and I want him to have friends, I would just feel more comfortable if he would look for male friends (especially when he doesnt have many friends in general). I tried to express this to him in calm conversation, I tried to show him this from my perspective (I also want to learn two languages which he speaks) so I could also find some male native speakers to help, and he said he wouldnt like that. He also said I give him less freedom (not in exact words, I dont remember exactly the way he said it). Am I overthinking this? Thank you!
Sorry for my English, I am not native speaker :)
