When I was at school there was a girl in my class, her name was Jane and she really was plain Jane, she did not dress well, wear make up or put out any airs to attract, yet men fell for her left right and centre. She was a pleasant girl and I got on well with her but neither I nor any of my friends could work out what it was she had that attracted so many men.
Personally, I am very glad I never had 'it'. Once I left school, both at university and at work, I lived in a very male environment and being a man magnet would have been really difficult. I was very careful even about going out with people I met at work. Gossip about one's private life can be so damaging.
I felt the same outside work. I grew up in a family where a woman's success was not measured in terms of her ability to attract men, the matter was never even mentioned. This lack of interest, never seemed to put off anyone who did like me and DH and I have been married nearly 50 years.
