Mentioned many times but I hate the flirty trait,in RL of course is harmless if you are secure.In sims 3 never name it flirty always!!! see it as the "Cheater trait" that is exactly what it is in sims 3.In RL flirty is glances,compliments and harmless petting etc,in sims 3 could be simple as giving flowers but can go to kissing and making out all right in front of you.
The trait is great to have on non played sims in town to add drama but if your sim wife has it you might as well prepare to constantly be at each others throats.Your sim will accuse of cheating lose relations hold a grudge and eventually kills your relationship.
I like unflirty trait and add it to created sims I may plan on pursuing.
