My female best friend is very open about all of this stuff and her issue is not with the lack of experience itself, but with the personality type that a lack of experience brings. A lot of people have massively varying views on sex, with some believing it to be an amazing emotional experience and others believing it to be simply a physical pleasure and nothing more.
Some people may not want to be with a virgin because it may convey a certain shyness, which is not to some people's taste. On the other hand, some women may seek it out!
Essentially, with all issues with this, you can't really say whether women are - as a whole - turned off by this. It's just a case of finding the right person.
