Sir: Petronella Wyatt ("Marriage? No, I'd rather live", 28 March) lists among her reasons for wishing to remain single the belief that "sexual attraction runs its course in two or three years".
Whilst I would not in any way attempt to dissuade her from the single life, if that is what she chooses, she should not be so dogmatic nor pessimistic. I have been married now for 16 years (to the same person).
One of the main reasons I chose my husband was sexual attraction, and I feel no differently about him today.
