When the woman has started her sexual activity, the hymen does not close when spending time without having sex.
The hymen is a membrane that covers the vaginal introitus. With the onset of sexual activity, this membrane ruptures and becomes thinner until it becomes imperceptible. After the rupture, the hymen does not reconstitute again. That is, once you lose the membrane, the woman will be left without that membrane.
THE vagina it's composed by muscles that are elastic and can adapt with enlargement and opening during intercourse, as well as with relaxation and closure at unrelated times. So when you spend time without having intercourse, the woman can feel and realize that her vagina is more closed. However, this sensation is briefly adapted with the beginning of the relationship.
Therefore, the sensation of closed hymen after some time without having sex is due to the elasticity of the muscles of the vagina and not to the closure of the hymen.
