Here is the link to that article you mentioned, Nicole:

It’s funny actually that you linked to the one about misconceptions we get about love from movies – I think these are related concepts. About both love AND sex culture embeds insidious ideas that are tough to shake off since they came to us so young. In particular myths about virginity (especially that first-time sex should be painful for the woman) create a lot of confusion for many women and often delay diagnosis and treatment for painful sex.
I hope that in future we see cultural examples that are more accurate and less fanciful – as fun as romantic comedies, for example, can be, they build a bad bedrock for real understandings of relationships.
