masturbating together?

My man brought up the idea, that instead of sex, we spice it up a little and just masturbate together. Has anyone else done this with their partner? I’m a little shy about it and not sure, so I’d just like to know if anyone else has, and if they enjoy it?

EDIT*

thank you everyone for your input, your comments made me a little more open to the idea and we’re definitely gonna try it! 😊
