OCD around consent

I have bad ocd. I'm in a relationship that's amazing and my ocd kinda attacks the relationship.

Currently, it's telling my boyfriend can't consent because of his bipolar. Its reasoning is that teens and preteens can't consnet because of their bad judgement, so he can't becuase his bipolar sometimes gives him bad judgment.

is this true? is the reason minors can't consenttheir bad judgment?
