I'm glad to hear someone speak up about women's enjoyment of sex. I have never in any way considered myself a feminist, but when I read some posts, or think about some religiously based sexual regulations (including burkas!), I cannot help but believe they stem in some way from a fear of female sexuality.
God gave us our sexuality and it concerns me to see it viewed as dirty, dangerous or a distraction from higher morality. Of course, I refer to sex in marriage!
And about lust--if it's for your spouse I think it's great!
Nothing in NFP speaks against enjoyment of sex by either spouse.
