I have been doing a lot of dog walking in an attempt to a) walk dogs and b) rebalance after a lot of time spent in front of a screen. Whilst doing so I have gone back over books old and new and put them on Audible to listen to while I tramp around the countryside.
One such book was Naomi Wolf - Vagina. If we could just get the first part of three parts I would be happy as it is brilliantly informative about the neurostructure of the female sexual organs. The second and third part of the book seems to abandon all medical sense.
However that I would really recommend reading or listening to is Mind the Gap. It discusses a whole host of topics around female desire and gives great advice on how to maintain and improve satisfaction.
Gurney's writing is very accessible, explaining things clearly without being patronising (and backed up by research, too). There are a few typos/some words appearing twice which could be amended in a future edition.
