I know you're quite young, and you would like education. So I'll share my experience.

It depends partially on the man. Some are easier to live with than others, the same as women.

My husband snores, for example, but that doesn't bother me. I take it as a "comfort sound." It tells me he's there, and that helps relax me. For other people, though, a partner who snores would be a problem, and it would disturb their sleep.

Now, the important part to understand is, there is much more involved in living with a man, besides sleeping in the same bed and watching TV together. You have to consider each other's habits. My sleep patterns have always been inconsistent, so if I'm awake at night, I have to be careful not to make noise or turn on a light where it will bother my sleeping husband. It would be very difficult for him to live with me if I didn't try to be considerate. Division of labor is a consideration. Who is going to do the cooking and the housework, especially if both of you has a job? Does he expect you to pick up after him? What are you going to spend money on, or save up for? Should one of you make a major purchase without consulting the other? How do you treat each other? Are you polite? Does he feel it's perfectly acceptable to insult you and call you names, because "you should be able to take a joke" or does he care about your feelings?

Then there are the little annoying things like whether or not he puts the toilet seat back down when he's done using it.

And no, you pretty much can't kiss and cuddle whenever you like, because at least one of you is going to have to earn a living for part of the day.
