This can refer to any item or object which is the most commonly used or which you use without having to think about it, such as a food, bag, facial expression, etc. Your 'go-to x' is the 'x' that you will resort to most commonly when you don't have the inclination/time to come up with something more original, or else that you will just go to automatically.

A go-to bag, for example, would be one that went with any day-to-day outfit and is suitable in pretty much any situation. If you're in a rush, you grab your go-to bag.

If you're feeling unimaginative, you eat your go-to food - something quick that requires little effort but tastes good.

The same principle can be applied to pretty much anything.
A: You look grumpy, what's up?
B: Nothing, this is just my go-to face.

A: Dude, all you have in your cupboard is pasta and tinned tomatoes.
B: Yeh I know, I haven't had chance to go shopping - pasta is just my go-to meal.

A: Do you know what kind of glue I should use to stick 2 pieces of wood together?
B: I dunno, I'd just use PVA, it's my go-to glue.

noun: A go to is the person you go to for sex on a consistent basis without it being a dating relationship. It is also the term to use when describing the fact that you are sleeping with someone but not actually dating or even "seeing each other". Its the term for the person you go to for consistently good sex and no pressures.

The term perfectly describes a relationship based soley on sex. Unlike "friends with benefits" which implies friendship that includes sex, the "go to" relationship generally starts as sex first. If a friendship develops it is usually a by-product of the sexual relationship rather than the origination of the sexual relationship. Different than a booty call or hook up, the go-to relationship is generally more consistent, which eliminates one or both parties from having to go out and look for it.... Cuz ya got a "go-to" for that!
Question: Are you dating anyone? Answer: No, but I do have a go to.

Question: What are you up to? Answer: My go-to is coming over for a bit then I'm going to the mall.

Question: Wow, he's cute...are you dating him? Answer: No, he's my go-to.
