Opinions on relationship..

So I met this wonderful guy through my older best friend. I'm 16 she's 18. We're gonna call my man mark to hide identities. Keep in mind mark is 23.. We both really like eachother.. But he is a BAD boy.. I can not say that slightly enough. It doesn't bother me and it's a turn on. Obviously my family would think differently but he has such an amazing sweet Side to him. 😭❤️ he treats me wonderful.. What are y'alls opinions on us.. Is the age gap to big..?
