Medical question, can it be bad for females to remain virgin?

Ok, i have always considered my self to be quite wise when it comes to information on sex. how reproduction works, how diseases spread. and all that stuff.

however, i have recently been given a very curious piece of information i did not know. and am trying to see how much truth there is in it.

i have been told by a girl, that if she does not lose her virginity before she is 30 that she runs the risk of getting some kind of disease or medical condition of some kind. does anyone out there know anything about this?

fluther was not my first thought, but a google search has turned up nothing. maybe due to my search having too many words in it. all i found was, top 10 reasons it sucks to be a woman and other things of that kind. but no information on this particular thing.

i would really appreciate any information on this as i currently find me self in quite a odd situation. at least odd for the likes of me.

please provide a source if you have a means of doing so. thanks.
