Whenever I unconsiously think about being married I picture myself with a wife and its hard to change that because when I was a kid I was always told "You will grow up to marry a woman." My parents werent against same sex marriage they just never mentioned it to me until I was 10 and I cant except my sexuality:bang:.
This is one of those things where you just gotta trust old farts like me when I say: your views will change with time.
Regardless of this, by the time you are thinking about getting married you'll be with a person you love! A picture you have in your head is very different oftentimes than what will likely happen and what will make you happy, but it also won't affect the future.
