Is vaginismus and dyspsreunia the same?

Vaginismus: When a woman has vaginismus, her vagina's muscles squeeze or spasm when something is entering it, like a tampon or a penis. It can be mildly uncomfortable, or it can be painful. Yes pretty much the terms refer to the same set of symptoms.

No: Vaginismus involves spasms and pain of the vagina, which can cause pain with intercourse (dyspareunia). Dyspareunia can be from any number of other issues as well. Finding out the cause of the underlying pain or dysfunction is important to get you to a healthy, pain-free state.
