<human>: Some context: I'm quite a reserved individual and though I have FB and Instagram accounts, I hardly post anything. My SO on the other hand is a social butterfly and he posts on social media constantly.

I know I used the word 'over-sharing' but I would say that his level of sharing is quite normal for most people -- however it isn't something I am comfortable with. For example, I made him a really cheesy Valentine's Day card and I didn't expect to see him put a picture of it on FB! He was really sweet but I was embarrassed by it. I feel obliged to reciprocate by posting similar things on social media because I know he really likes it! If I don't, he'll ask me directly: "You should post my Valentine's Day gift to you on my FB wall!". He puts up pictures and posts of all the dates we go on and all the gifts I get him! Everything! 

I've approached him about it before but I don't think he takes my concerns seriously. Granted, I didn't make it a big deal out of it either so he's continued to do this. Am I being overly sensitive and should I just suck it up?

Can you give me the gist of the text in a nutshell?
<bot>: Social butterfly SO's lovey-dovey posts on social media about our relationship make me feel embarrassed because I'm very private. Am I just being overly sensitive?
