Wife suggested we (I) watch porn

So last night after a few glasses of wine my wife suggest I could watch porn with her, but then she said she wasn’t sure if she wanted to actually see it or just be with me while I watch it. Since my wife doesn’t /hasn‘t watched porn I’m not sure what she is really expecting. I’m thinking this is something she and a girlfriend came up with. The only porn I would really enjoy watching is mature, amateur woman masturbating.

Im curious if any other couples are together when one is watching and the other is just listening and or there for support? I just not sure what this dynamic would be like but I’m very interested in trying it, but want to avoid any pitfalls.
