how do i find the porn my BF was in?

I just found out that my boyfriend did a couple porn videos a while back. At first I thought I didn't want to see them, but not curiosity has gotten the better of me (a few details left out as to why i feel i need to see them now) Any ways, My bf told me about these porns only because i had confronted him a few times about why we never have sex (3 times in a year) he finally told me that he did these porns at a low point in his life and that after doing them he felt like a prostitute. he regrets doing them. and now when he tries to have sex he just feels dirty and cheap. resulting in us hardly ever having sex.

How do i find these video/s? I would normally just ask him. but when he told me about them he told me that the only reason as to why he informed me is because he felt i deserved the answer and didnt want me to think that the lack of sex actually had anything to do with me. He said he doesnt ever want to talk about them again. But, I told him that i need to talk about it again at least once. I explained to him that i wont bring it up again until i have time to process everything about what he just told me and have everything together that i need to say.

I think I need to see the video/s to figure out how i truly feel about it all. Only problem is, i have no clue where to look. I have a close estimated time frame as to when it was filmed and i know what city it was filmed in. I also have some good ideas as to what tags it may be under.

Does anybody know of any ways to possibly track down the porn/s he was in?
