Is there a site where you can find out the average age a man becomes a father for the first time?

Answer 1

Since nobody else has given you an answer, I'll answer even though I only have information on the age of mothers at first birth: " Another useful measure in interpreting childbearing patterns is the mean age at first birth. The mean is the arithmetic average of the age of mothers at the time of birth and is computed directly from the frequency of first births by age of mother. In 2003 the mean age of first-time mothers was 25.2 years, slightly higher than the previous record high set for the United States in 2002 (25.1 years) (table B). Mean age at first birth rose for nearly all race and Hispanic origin groups.However,considerable variation still exists. API [Asian/Pacific Islander] women had the highest mean age at first birth in 2003, 28.3 years, whereas American Indian women had the lowest, 21.8 years. The average age of first-time mothers was 26.2 years for non-Hispanic white, 22.7 years for non-Hispanic black, and 23.1 years for Hispanic women." http://www.cdc.gov/nchs/data/nvsr/nvsr54/nvsr54_02.pdf page 6

There is a lot of information about fathers at the same site; I did not see the precise information you seek, however, but it might be there someplace. It does note that information about the father is often missing if the mother is young and/or unmarried.
