Like others here I'd say that when you start thinking about it, think of it as options. I wanted a water birth with gas and air. I ended up having water birth but not in the lovely pool in the midwifery led suite but in my bathtub where I sat to relax and manage pain of early labour. However, by the time MW arrived to asses me and decide if it was a hospital time or not, I was pushing and I had my baby at home (got out of the bath for that though). Definitely not what I planned as a preferred option so I remember being on all fours by my bed being told to push and thinking "Well, this is WEIRD!"

Have series of options and bear in mind that they may not be possible. And remember that when you're in labour things can change very quickly.
My plan accounted for me as well as in, how I behave when under pressure. So knowing that I have propensity for impulsiveness and impatience, I requested that if I said that I wanted pain relief beyond hypnobirthing techniques and TENS machine (and gas and air which I had for the last 15 mins anyway), I wanted to be explained clearly the risks and benefits concisely and questioned ONCE at a time i.e. If I say I still want pethadine/epidural after the explanation, then don't hold it back or try to persuade me again. This was handy as when I started dilating rapidly I suddenly threw all the hypnobirthing birth stuff to the wind and said I wanted to go to hospital rather than wait for MW as I could not "fucking do it anymore". My birth partners simply explained again what it meant and I returned to breathing exercises out of my own volition knowing I could ask again. Also I requested that nobody asks me if I want epidural/pethadine - if I want it I'll ask for it myself. Important for the epidural bit - ask to be informed when there is a point when it cannot be administered anymore. I had an order of drugs as well: gas and air, then pethadine, then epidural.
And if you're using tens machine, test it beforehand and get lots of batteries. I sent my DP out to get more batteries as I couldn't bear possibility of it running out of juice 😆. We have A LOT of tiny batteries knocking about as a result.
I also had two people at my birth. My partner and my female friend. While I love my DP dearly and he's a kind patient man, I wanted him to have a back up too - my early labour was slow so one of them was resting while the other was looking after me/keeping me company. On couple of occasions I found it easier to explain to a woman what I needed and she was quicker to spot what I needed and when, purely because she's been through a labour herself. She also had a calmer head on as she was not as emotionally attached. Plus she filmed the birth and took pictures while DP was busy holding my hand and getting immersed in watching our baby being born. They were a great team.
When it comes to "natural birth*" I'd say that baby's position is key. If baby is engaged and in a textbook position for birth (facing back) - if baby is in an awkward position that allows vaginal birth there is a likelihood that you may benefit from more medical intervention so discuss this with MW beforehand and agree on best approach.
And whatever happens and however baby comes out, you've given birth and are a bloody Goddess for doing so!
HTH
*Small point. Maybe it's just me but all births are natural as far as I'm concerned. Vaginal birth is just one of the options. 😉
