My boyfriend says he snaps only his friends and not some random girls, should I trust him?

I recently asked my boyfriend who is he sending snaps through the day, assuming there are some girls. His answer was that he snaps only his friends and he is doing nothing wrong and that I don't have enough trust in him... Should I believe in his words or do something about it? We have been dating for like 5 months and we recently started our relationship serious.
