Generally, Tamil Nadu is one among the safest places in India. But like any other tourist destination, there are a few problems. Beware of pickpockets and thieves in Buses and Trains. If you travel via Train, think twice before eating anything offered by co-passengers.
Also, when traveling with someone from the opposite gender, it would be advisable to avoid too much of physical intimacy, as it may invite unwanted attention and comments.
It is also best if you do not talk about the Sri Lankan Civil War between the mainly Sinhalese Government and Tamil fighters.
