I flashed my aunt.
Why did you expose yourself to your aunt?
She wanted to see it. She's always shown me her chest even though I told her it makes me uncomfortable.
I'm sorry to hear that your aunt did that and made you feel uncomfortable. What she did to you is wrong and you don't need to put up with it, but you still shouldn't expose yourself to your aunt. It's wrong to do sexual things with people related to you and you both need to stop.
Anything sexual just makes me extremely uncomfortable now and I'm already a teenager.
That might be because of what your aunt did to you. I really hope it hasn't been happening for too long but as a teenager you should tell someone that she's been exposing herself to you and asking you to do the same. What's she's doing is disgusting and is taking advantage of you.
