Confusing libido

My boyfriend and I have been together for a year and I just recently have been getting kind of bored with our sex. I am completely obsessed with him and love him more than anything, but recently he has stopped pleasuring me as much and he’s said in the past how a healthy relationship needs to have sex frequently so it feels more like a chore. It feels more like I am helping him feel better and keeping him interested rather than it being mutual. I kind of want to bring a vibrator into our sex to help me, but I have a lot of trauma associated with sex toys. My ex boyfriend sexually abused me and would make me use sex toys. I feel like using a vibrator would help me, but I am nervous about using one. I did tell him that I am getting bored with our sex, but I would love some advice and how to talk about this with him.
