Ease Me In (The more guarded approach):
I chose my birth control method for a lot of reasons, but I care about you and youre the other half of this relationship. Can you tell me why you prefer another method? Maybe we can try to find some middle ground.
Just Give It to Me (The no-nonsense tactic):
This is my body and I feel like I should have ultimate say about what I use for birth control. If you dont like my choice, tell me why and give me some alternative ideas. We can put sex on hold until we find one that we both agree on.
