Is this sexy or bad???????????????????????????…

I'm skinny but have a big ***....I have to wear a size 7 in skinny jeans & its REALLY tight on my booty but its too big around my waist...but my jeans go way up my crack lol I think its sexy & so do guys but at school girls say "ew your jeans ride your a**hole..." I'm not doing it on purpose...does that look bad like should I stop wearing skinny jeans??
