Even though they don't often like to admit it, sometimes men need a little help.

Men's Health magazine decided to take a look at which major U.S. cities most need a little Viagra.

To come up with the rankings the magazine studied several factors, including risk factors for erectile dysfunction such as obesity, smoking and diabetes. They also noted how many urologists were in the town, as well as number of prescriptions for Viagra, Levitra and Cialis.

The 10 cities most in need of help were:

1. Tulsa, Okla.
2. Lubbock, Texas
3. Charleston, W.Va.
4. Arlington, Texas
5. Fort Worth, Texas
6. Oklahoma City
7. Anchorage, Alaska
8. Bakersfield, Calif.
9. Modesto, Calif.
10. Omaha, Neb.

The magazine also provided an interactive map that allows citizens to see where their hometown ranks in the several categories.

Men in Boston had the best sexual health, according to the ranking.
