Does Katniss do it with Peeta in The Hunger Games series?

Answer 1

Yes. However, it is a very subtle remark and you must have a keen eye and good reading comprehension to catch it. Katniss begins the illusion to sexual content by saying "On the night I feel that thing again, the hunger that overtook me on the beach, I knew this would've happened anyway." She then goes on to talk about why she needs Peeta and not Gale. After this section, Katniss's narration says "So after, when he whispers "You love me, real or not real?" I tell him, "Real,"". The "so after" that is included in that refers to after they engage in sexual activity.

This is the whole final paragraph of Mockingjay.

Peeta and I grow back together. There are still moments when he clutches the back of a chair and hangs on until the flashbacks are over. I wake screaming from nightmares of mutts and lost children. But his arms are there to comfort me. And eventually his lips. On the night I feel that thing again, the hunger that overtook me on the beach, I know this would've happened anyway. That what I need to survive is not Gale's fire, kindled with rage and hatred. I have plenty of fire myself. What I need is the dandelion in the spring. The bright yellow that means rebirth instead of destruction. The promise that life can go on, no matter how bad our losses. That it can be good again. And only Peeta can give me that.

So after, when he whispers "You love me, real or not real?"

I tell him, "Real."
