This is really hard to define as it depends on the people involved.
The solid grounds for a good relationship is trust and respect.
This means being able to be open with each other and respecting each others needs, opinions, and having the ability to work through things, like rifts and jealousy.
There is so much more to relationships than holding hands and how often you call each other.
It's when something terrible happens and how you cope and deal with bad situations that counts.
A turn off for men can be when women are possessive, and vice versa. Jealousy taking over can affect relationships, as can too many arguments over trivial things.
How fast or slow you take it doesn't always make a difference, it's how you make it work that counts.
