Too scandalous for Instagram?

I bought these SUPER cute booty shorts at Warped Tour from one of my favorite bands (Ice Nine Kills, as you can see) & I'm like DAMN DO THESE MAKE MY BOOTY LOOK NICE. I have worn them out in public, b/c its been super hot (& I also tug them down a little more too). But I took this cute pic & I so badly want to post it on Instagram, but it's kind of scandalous. My 11 year old cousin follows me on insta, & so do my older cousins (older than me (I'm 18)). So I'm afraid they would nark on me, or I'm a bad influence on my younger cousin. I've posted bikini pics before, but that's different I guess. I'm also afraid that creepers will, well, creep. My account is set to private, so only people who follow me see my pics, but there's a few guys I know that are creepy. I also suspect me Ex is stalking me from his friends account, but I wouldn't mind if he saw this. I kind of ranted, sorry about that, but I'm torn.
