Oh really? I think as fast as you can. As soon as you know the real meaning of responsibility, you should married.
I got married at 22. I think my ideal age would be around 28 which I am now. But none the less I'm glad I got married young.
My ideal age to get married would be 27. I think that's enough time for you to earn enough savings before settling down.
I think male and female difference of age should be 5 years, female should be younger than male, 25 to 30 is ideal age, keep distance from GF
