This thread is what is so valuable about MN, it shows people posting a whole range of experiences. While there are some common threads, it also shows the huge variety. It's an important topic, and great is not hidden away in the Sex topic section.
Yes, there is indeed a risk it can be wank fodder, no more so than the Relationship section can be misery fodder. I have a few RL friends on the forum, but have NCed for this post.
The @Echobelly post resonated with me (great band btw!) but only in some ways. I'd had a sexually repressed upbringing, assaulted as a teenager, religious environment and was not very body confident.
My friends would talk about masturbation, orgasm, and I generally avoid the discussions. I'll be honest and say it was a problem with my first serious BF, and later with DH. Looking back, being with a longer term partner that does not orgasm must be difficult (if sex is an important part of your life).
It was a journey for me. In my 50s, with kids older, after some health issues, and a change to a new GP (younger, female), starting HRT that I took the time to explore, try things, and figure out how I worked. So I my first orgasm in my 50s. I know myself/body better than any time in my like, and I mean in general terms with respect to food, drink, exercise, sleep and so on.
In summary, I think there is a lot to be done with respect to education and female sexuality. More should be covered in schools for sure, but I think media/books/TV have a role too. Also GPs could be more supportive too.
