It is good to read articles on the subject, to expand our common culture, but it will be best if we talk frankly about it with our partner.
Guys, do not be ashamed to ask. No one should expect that you know everything about the female body, soul or read her mind. Every organism is an individual universe, and it' is a great opportunity to dive into it.
Girls, be honest. When you do not feel the necessary sexual drive - talk to your partner. Perhaps you need to reveal more about what really gives you pleasure, direct him, encourage him, and thus achieve a strong orgasm. If you do not know yourself, where the G point is, experiment with yourself when you are alone - learn more about your body. If you do not know yourself, how do you expect this from men?
