@Aether Keep in mind that these "never had a boyfriend" types differ greatly from guys who "never had a girlfriend." Unlike those men who are also likely virgins, these women who "never had a boyfriend" are very likely to still have had a string of casual sex partners or "situation-ships" where they sleep with a guy but have no official relationship.
Also, it is not as if they could not have a boyfriend if they just make their standards more reasonable.
