1 Corinthians 7:3-5 The marriage bed must be a place of mutuality—the husband seeking to satisfy his wife, the wife seeking to satisfy her husband. Marriage is not a place to "stand up for your rights." Marriage is a decision to serve the other, whether in bed or out. Abstaining from sex is permissible for a period of time if you both agree to it, and if it's for the purposes of prayer and fasting—but only for such times. Then come back together again.

You and she are in serious need of marital counseling, and I don't mean from the WT.
Peace to you, Lil Brother.
