When I replay Mass Effect with the Male!Shep, I'm planning on romancing Kaiden. I have to wait fully two games to do so, but it'll be worth it, hopefully.

I never disliked Kaiden, to be honest. It's just I was going for the full gamut of biotic potential (ME1: Vanguard, ME2: Adept, ME3: Sentinel) and Kaiden didn't quite fit.

I'll be dropping Ashley though for my Soldier/Infiltrator/Engineer playthrough.
