Vibrator during sex!!

Me
So yesterday was my peak fertility day and my fiancé knows, and I think knowing makes it a chore for him, which to be fair I totally understand, 
He wasn't in the mood. And he's saying, it's not his fault and again I totally understand, and I was thinking, what do I to get him going, then I just grabbed the vibrator that we got last year and never even used because I'm shy and embarrassed to.  
So 
It was my first time using it last night, and that FOR SURE got him going, 
So, for any of you with this same problem, like it's a chore, 
Just tease, and for sure you'll get the BEST SEX EVER!! 
Sorry if this seems so out there, but had to do something :(
