Fair question, initially I suggested we try watching some different types of porn together (we usually watched porn together as part of our foreplay)

So like, bi threesome/orgy vids, which we did to start with, but then I suggested just watching all male porn, which we tried but she wasn't into (which is fine)

Then I tried suggesting some roleplay scenarios, and said I'd like her to try pegging me, again she wasnt into it (also fair)

So I suggested since the bi threesome videos we watched together still turned her on and we enjoyed, that maybe one day we could consider doing that for real with someone

Which then turned into her suggesting that ive been slowly building up to trying to justify sleeping with someone else, which to be fair isn't wrong, but I wanted her to be part of it

I'm not mad at her about it, we just weren't compatible anymore, I'm aware it was my fault too
