I don't mind getting "invites" from Gale or Wyll as a male PC, but I think they should still work a little more on the system as a whole.
When having slightly high reputation with companions let them have some lines with a [Flirt]-Tag. So I can decide who I am interested in. Maybe I want to romance Gale, but just be best buddies with Wyll. This should not be decided by which of them I take my first chance to sleep with. There should be some build up to it and my best buddy should not try to squeeze benefits out of me.
