For women who have never had sex or given birth, the vaginal muscles are tight and not affected by other factors, so there is no relaxation of the vaginal wall muscles, so the tightness of the vagina is a normal physiological manifestation and the vaginal wall muscles are very elastic, so the tightness of the vagina does not affect a woman’s sex life or fertility. This is because after pregnancy, the placenta and ovaries secrete various hormones that cause the muscles of the vaginal wall to relax and expand so that the fetus can be naturally expelled from the vagina during delivery. However, if a woman’s vagina is too tight due to a vaginal deformity, this can affect her sex life, so she needs vaginoplasty to correct the deformity.
