Opening the legs during ovulation means that during ovulation, due to changes in hormonal levels in the body, the leg muscles relax slightly and the leg joints open slightly. This physiological phenomenon usually occurs between the 14th and 19th days of the ovulation period, and this process is also called "ovulation leg opening."

Additionally, some may think that spreading your legs during ovulation is a sexy sign, but in reality, there is nothing sexy or suggestive about this behavior. Instead, it may be considered a natural physiological phenomenon and may cause other physiological responses, such as changes in hormone levels in the body and muscle relaxation.

Generally speaking, spreading the legs during ovulation is a normal physiological phenomenon, and for many women, it does not cause any discomfort. But if a woman feels uncomfortable during ovulation, or finds the behavior sexy or suggestive, she may want to put the practice on hold and seek medical advice.
