In more than one-quarter of gay marriages, the age difference was more than ten years. The average age gap between lesbian partners was 4.6 years, versus 4.3 years between heterosexual partners.

Whats a normal age gap?

Most men marry women younger than they are; with the difference being between two and three years in Spain, the UK reporting the difference to be on average about three years, and the US, two and a half. The pattern was also confirmed for the rest of the world, with the gap being largest in Africa.
