I don’t think any woman can find an absolute and unequivocal answer to this question, and I frankly don’t believe that such an answer exists, as it would heavily depend on that specific woman’s goals and needs at that specific point in her life.
An older woman might have the greatest time of her life dating an energetic, exciting, attractive young man, but she is also likely to feel that she is wasting her time being with a younger guy and knowing that it is not going to turn into a long-term relationship, instead of pursuing a relationship with a man with whom she could establish a family and have children in the nearest future as the biology would dictate to a woman who is aware that her biological clock is ticking.
Many younger guys are driven to women who are 10 years older than they are or more, as these women are often more confident and more sexually driven and passionate than the younger women.
These younger guys are both curious and excited about dating a woman who, is not ashamed of what she wants sexually, unlike the younger girls of his own age who are often confused about just about everything, including their romantic and sexual desires.
No woman is attracted to a guy who is a couch potato or who is unable to climb a set of stairs without being out of breath, especially if the woman herself is very active.
