So, I'm curious. Since most health insurance carriers don't cover things like Viagra, where do people go to get it that is safe?
I'm not following the logic. Just because insurance doesn't cover a drug doesn't mean it's unsafe. You still need a doctor's prescription to get Viagra, and you would get it at a regular pharmacy just like any other prescription, you just have to pay for it out of your own pocket. Viagra is a [relatively] safe, FDA-approved medication.
You can go to online pharmacies which are located outside the United States, and buy "generic" Viagra without a prescription, for much less than the $20 per pill that real Viagra presently costs at a U.S. pharmacy. The "generic" Viagra is produced by companies which do not honor Pfizer's (the make of Viagra) patent, and sell it on the foreign market in violation of their patent rights. I'm not making a value judgment here; I'm just telling you what's happening. People have had variable experiences with the quality of these generic Viagra knock-offs, and with the pharmacies that sell them.
Some of the generic Viagra (sildenafil citrate, the active ingredient in Viagra) is claimed to be of high quality, made by overseas producers of the actual Viagra, and other major foreign pharmaceutical companies like Ranbaxy. Other generics are produced by fly-by-night pharmaceutical companies in China and other countries, and have been tested to have little or no sildenafil citrate in them, and sometimes contain other medications that vary from benign to dangerous. Likewise, some of the offshore pharmacies ship good product and do so reliably, while others rip off the customers, steal their credit card numbers, and so forth. You can find reviews in a number of places, including here, for example:

Obviously, you're also buying a product illegally and without a prescription, and in violation of patent laws, and you can have issues with U.S. Customs - some fraction of the orders are seized during shipment. Again, a reliable pharmacy will make good and re-ship, while a bad one will simply screw you. You take your chances. Look at reviews of the online pharmacies, and try to get recommendations from people who've had good experiences.
Pfizer's patent on Viagra expires in March, 2012, at which time lower-cost generics will become available in the U.S. You will still need a prescription.
