How can we have a marriage if sex is physically impossible?

Creatively: Intimacy doesn't have to be sexual. And marriage does not have to mean penetrating intercourse. The most important thing is to communicate. Both of you, as a couple, will figure out how to be intimate. Remember, fingertips and lips have as many (or more) nerve ending than genitals... As the say, the mind is the most errogenous zone there is.

Sex: We touch bodies when we have sex, we only touch souls with empathy and compassion. I know many couples who cannot have sex for various reasons but remain in love and very affectionate through words and the love of each other's character. Best.

Find ways to comfort: Our primary need is intimacy, and there are so many things outside of intercourse that constitutes intimacy. Have an open/honest discussion about your desire to be intimate; talk about what you can do - bathe together, lie naked and hold each other, give massages, cuddle. Some of this will make you sad because it will remind you of what you've lost, but better to experience that grief together.
