I romanced sera twice on my qunari rouge playthrough and Cullen on my mage elf playthrough. I don't know why people saying that Sera's romance is worse when you pick a specific race that totally fits her (dwarf or qunari) it's actually quite an adorable romance imo especially in the trespasser dlc.
I ended up making the relationship between my male and Josephine being a platonic one after the talk with Leliana which he does secretly harbor some true feelings for her and the origin name of his famous bow... just like Bianca.
Siding with mage over templars? No Problem. Leaving a grey warden to fight a demon? No problem. Let a witch drink from the well which resulted in subjugation to her own mother. Definitely No problem at all, but playing with a male inquisitior relationship is problematic for me imo.
