If by physical intimacy you mean sex or sexual activity: there is no medical time limit for how long a woman can go without it. A woman can live a perfectly healthy life without sex indefinitely.
Not having sex does not cause the body to “fill up,” become unhealthy, or stop functioning. Sexual desire varies widely—some women want sex frequently, while others are comfortable with little or none.
What can change is how someone feels emotionally or physically. A lack of desired intimacy may lead to loneliness, frustration, stress, or sadness, particularly when intimacy is an important part of a relationship. But those effects are about individual needs and circumstances, not a biological deadline.
If you meant what happens to a woman’s body after months or years without sex, I can explain that too.
