Hi Precious,
I honestly wouldn't even consider this a lie, just not knowing what to say in the moment or feeling comfortable saying it. I think it's up to you. If you want to start to talk about the areas that you consider traumatic, you can just tell him you've reflected on his question and have a different response than in the intake. But maybe you're inability to voice it was good intuition that you need more time to build trust and a relationship with your new t before you can get into that.
Hugs to you.
