I've been wearing an amulet of Mara for quite a long time, but I haven't had the "Interested?" dialogue option with any NPCs I've met,
ever. However, I just purchased the house in Windhelm, and became Thane, and my new Housecarl (who is male) asked me if I was interested in him the first thing he did. I wasn't, really.
Is this a bug or something? I can't even ask a lady out, but male fighters seem to have a thing for me.
Help please?

I don't mind if he's into me, but I'm not into him. Sorry.
