With regards to Martin, if anything happens with regard to D and him, it would only be with the consent of F and would be completely 100% avoidable, so there is an out. Plus you can always just toggle the Martin/D sharing off by clicking on her picture. For example in my playthrough I can't let him dance with her and she doesn't sneak a peek either. In other words in my playthrough as it is nothing will happen between Martin and D.
D and Elena, yes
D and Olivia, yes
D and Margo, yes
D and Georgina, I hope so
D and Jen, maybe in the future.
But D with another guy, nope not happening for me. Yes totally hypocritical and frankly don't care.
