Should I be bothered that my boyfriend follows attractive women on social media he meets in passing?

He recently started doing uber a few months ago and I noticed a big uptick in women he follows/friends on social media. Now we are in our mid - late 30's and these are mostly attractive women in their 20's, like college women and I'm like what on earth could you possibly have in common with them? why the need to follow and friend women you meet doing uber? Maybe I'm being insecure. I'm also bothered that most nights he does uber it's until 2-3 in the morning and combined with this I'm concerned.
