Nothing in NFP speaks against enjoyment of sex by either spouse.
It has been posted here that lust makes sex sinful in God's eyes and that abstaining from sex in marriage is beneficial spiritually.
As far as NFP and women's enjoyment of sex, I was referring to the fact that women are more "receptive" during their fertile times, exactly when one abstains in NFP. If other methods of sexual pleasure during that time are acceptable, then that negates that issue.
