porn/sex😝😝

I know my husband watches porn behind my back, it doesn't bothers me at all, bacause sometimes i also do it to increase my sex drive! Lol 
And i kinda want to spice things up and been wanting to tell him to watch it together, but i feel embarrassed 😬🙄
How should i come to him and tell him? He has tell me before but i just act like i don't want to lol
