Hi,
generally speaking, you'll be fine - people there are very nice. You will meet huge amounts of expats working there also which dilutes the local population, everything from the highly paid EU/US/etc to the many Indians, Pakistanis, Afghanis, Philippinos, etc that do the real hard work and drive taxis, clean rooms in hotels, etc., for a small amount of money by our standards. Treat them with respect and they're very helpful and a great source of information.
As far as the locals are concerned, most are fine - but some, especially the well-off ones, can have a twisted view of women - their own should be covered up and chained to the kitchen table, but foreigners are seen as "loose" and viewed more like porn stars. Actually, in Kuwait, women are more liberated there than in many other countries in the Gulf. In any case, if a local hits on you, just given them a very firm (don't beat around the bush, it doesn't work), but polite "no" and they'll leave you alone.
As with all countries, just remember where you are - if it doesn't feel like home, that's because it ain't, and you shouldn't treat it or act like such. Learn the local customs and respect them, and a few words of Arabic always help.
