can having a family bed hurt ur marriage?

Aside from the concerns about the health of children, what are the pros and cons of the family bed for parents? Can having a family bed hurt a marriage?
The biggest concern seems to be a fear of losing intimacy, and of not being able to have sex whenever a couple wants. Some couples do find that their sexual intimacy is lessened. Others find sharing a bed with their kids just makes them more creative in finding other places in the home to have sex like the sofa, guest bedroom, futon on the floor, shower, hot tub, carpet, etc. These couples say that this adds spontaneity and spice to their lovemaking.
If your own space and privacy and the need for a good night's sleep is important to either one of you, or if the two of you can't agree on this issue, then having the kids in their own beds is probably best for your relationship.
Co-sleeping doesn't necessarily mean a king sized bed with everyone in it, though. Some families have the crib or an additional mattress or futon next to their bed. Open-door policies where children have their own bedrooms, but are allowed free access to their parents' bed is another option for families.
