Why does it take some people longer to achieve an orgasm?

To elaborate, what are the differentiating factors (physical vs. mental) that determine how long it takes for a male or female to achieve an orgasms? Like, if there was a scientific formula, what would it look like?

There are a lot of different hormones, neurotransmitters and cell wall receptor sites that are involved with orgasm in males and females:
Testosterone
Estrogen - estradiol
...
Prolactin - too low or too high - no joy
Dopamine
Seratonin
Oxytocin

Also, innervation of the relevant tissue - there is not a fixed number of nerves per unit of area in humans - add in life experience, drug use, epigenetic and genetic factors - you're going to get some variance.
