How to bring up using a toy?

My boyfriend & I have been together for 2 yrs. we were each other's first and have only be with each other. I love having sex with him and we have such a power connection! 
But, I have never ever not even alone had the big O.. I've been reading post and stuff online that sometimes just vaginal sex isn't enough for some woman & they need a little help. Briefly in the past I brought up getting a little vib for me to use while we have sex. He got so upset about it that I never brought it up again until today. It's a new year, a new start to start using an trying new things and I'm really hoping he'll open up about using one..
How many of you girls have had to do this?
