It may surprise you to hear this, but an amazingly high number of people are not aroused during sex. For many women, being able to relax into a sexual experience is a rare occurrence.
Women often need more transition time – to shed their other roles and responsibilities, and shift into a sexual experience. You may need an hour to unwind and leave your To-Do list behind if you are extremely busy. When the initiation of sex happens at 9 or 10 pm, this is not very likely to take place.
