The Creighton Model refers to this as SPICE: Spiritual, Physical, Intellectual, Creative, and Emotional.
You avoid genital contact, but not sexual contact. You communicate in non-genital ways.
Spiritual: prayer, verbal communication of love and appreciation. Developing ourselves spiritually and putting God at the center of the relationship.
Physical: Hugging, kissing, holding hands, cuddling, back rubs, learning the difference between affirming touch and arousing touch. Physical expressions of love and intimacy between the spoues AND with the children (hugging, playing, kissing, etc). Also, physical activities done together such as walking, sports, etc.
Intellectual - gorwing as a couple with reading material, shared discussions, discussions about the family. Verbal intimacy.
Creative/Communicative - doing special things-- a dinner, a creative gesture of love, fun and romance. Doing something for the other person-- around the house or something that says “I love you”. Thoughtful gestures. (this is similar to the Love Languages book, finding ways that communicate love in your SO’s “love language”)
Emotional/Psychological: Reserve special time for yourselves to talk, away from children. Practice putting spouse first. Expres feelings. Be supportive. Vent frustrations and find appropriate ways to deal with issues. Create bonding time together.
