Living together

I agree 100% with aedak, and the same goes for women, you don't want to find out that your boyfriend is a complete slob and lazy butt, after you marry him because he won't feel the need to change and it will set up a bad beginning to your marriage. If your guy is serious about your relationship then he won't put off asking the question just because you live together, it will make him less apprehensive when he finally does.

Guys want to live with women before they marry them because it helps them understand if they will be able to tolerate them on daily basis. Things are generally MUCH different once you move in together, even more so than if you spend say an entire week with one another 24/7. If you aren't sick of each other by then, you probably will be unless you're 'perfect' for each other.

My best friend got married in June, he hadn't lived with her before and there were a lot of quirks to work out. She won't even let him use the toilet adjacent to their bedroom. Interesting question. I don't think your assumption that you will never be asked because he will think marriage isn't necessary is completely off, guys want marriage too - when they are ready for it.

I think its would be a good idea to live with the guy before you are married. As for me I used to really want to get married now I just want to be happy and have an commitment for my on and off boyfriend on close to 5 years.
