Vaginal tightness is mainly caused by the lack of elasticity of the vaginal walls and the developed muscles of the pelvic floor. The vagina becomes relatively lax after sex and after vaginal delivery, and if you don’t pay attention to recovery, some women may also develop vaginal laxity and even pelvic organ prolapse. A tight vagina is good for women who are sexually active, it can improve the relationship between husband and wife, but if it is too tight, it can cause pain and discomfort during sex and even damage to the vaginal wall, and it is not good for a normal delivery, as the fetal head can be obstructed when descending into the soft birth canal due to a tight vagina, and even hypoxia can occur. Women with tight vaginas can use lubricants during sex to improve the discomfort.
