I'm new to TRP so I'm just trying understand what she's trying to do here?

This fat girl I fucked from Tinder. Actually she is obese not fat.

Shes got a pretty face but still the body is gross.

She is trying to lock it down with me after I fucked

She keeps saying "Do you know how many guys wanna date me or be my boyfriend?"

And I just laughed and said "lol ok"

What is this mean? She is trying to validate herself?
