My girlfriend and I have sex atleast 3 times a week and we have dirty talks on the regular. Every time we dirty talk she brings up these words that are related to porn such as "cream pie and deep throat" and so on and even talked about guys who like getting their assh*le licked, out of nowhere, this obviously is suspicious. She said she hasn't watched porn since she was 11. She's now 19 and I can't imagine somebody remembering something as random as that out of nowhere. We were also just talking dirty talking and joking around and she said something about p*rn tags and the p*rn layout. She even said she wants me to j*zz in her so the j*zz will leak out of her vagina. Enough proof right? But I'm not done, she also deletes her history on her phone and laughs and tries to change the subject when I ask why. She acts shady when I borrow her phone. Every time i ask her if she does she gets mad saying "you never believe me". I get upset with her ofc because she banned me from it with the reason of it being related to cheating in a way. So if she watches it that's complete bullsh*t. Anyways is there any way I can catch her or atleast make her confess?
Now I know a lot of people are going to be saying that it's normal and healthy but her lying and telling me no more porn and her watching is just not fair. So I'd like to you know, prove a point and finally catch her.
Please help and try to understand thanks
