I would think that you would work out all the details around bills and housekeeping *before* going into any shared housing situation, regardless of gender.
I think the key thing is to realise ahead of time that theres a subtle but important difference (IMHO) between being roommates and renting a space from someone. Roommate situations tend to be more friendly, its not that big of a deal for example, if you take the last soda as long as you replace it. Renting space on the other hand is more transactional. This person is your landlord, not your friend. You leave their things alone and vice versa. You should pre-determine ground rules for everthing including acceptable noise levels (tv, stereo), if they have any cooking issues (on TTer had a neighbor complaining about cooking smells), and rules on having people over. If they have people over for dinner, your not invited unless, well your specifically invited and vice versa.
PS: In either situation, definitely settle any out of town visitor issues, so that you know ahead of time if and for how long your wife and two kids back in India are welcome to visit, and how much more in terms of bills you should pay during their stay as 3 additional people eat up a lot of space, water, and electricity.
