<human>: We've been together a few months now and things are going swell. We're some 150 miles apart (she works, I'm in grad school). We see each other every or every other weekend depending on how busy we are and it's good so far.

One small hiccup: our presence on social media. By nature I'm a pretty private person and keep a small group of friends. I only share relevant stuff with my close friends and I am not prone to advertise my life, I think its a bit frivolous. Yes I have a Facebook, Twitter, and IG but I use that to keep a tab on what's going on in the world but just so I'm aware and in the loop. 

She's a bit of the opposite.

We've recently become followers of each other on Instagram (IG is shorter for my convenience) and we both have browsed through each other's IG's to look at old pics as I'm sure everyone does. Little comments here and there, the usual.

BUT this is where my problem begins. I have some family/friends on IG but as I said, not everyone I care to advertise my relationship(s) to in general because it's called a personal life. Some of her comments are pretty G/PG but quite a number are saucy and flirtatious (PG13/R). I'd rather she not post such things on my IG but I don' t know how to tell her without sounding like an asshole. I've begun to field questions from people I don't care enough to share about my personal life and it's kinda annoying to be honest.

What's the best way to tread this delicately but not come across as an asshole?

Can you summarize the given text in a few sentences?
<bot>: GF's comments on IG are a bit too much for my personal comfort. How do I tell her to be mindful?
