Half people say it does, half that it doesn't.
Among the half arguing that it didn’t, there is a further divide: the men who didn’t care about women’s pasts because they had no intention of ever ending up in any form of committed long-term relationship... and the men who didn’t care because they legitimately thought a woman’s past had no bearing on her future.

Why should you care?
a 2007 study of American women,"Sexual infidelity in a national survey of American women: Differences in prevalence and correlates as a function of method of assessment.,"discovered a 7% increase in infidelity risk per each additional partner (also, a 10% decrease in infidelity risk per each additional year of education) for women.

You may be surprised to know that 1 out of 10 children born in marriage in the United States are not fathered by the husband in that marriage, or carrying a permanent infection from one of her past partners.

When did she first have sex
Has she ever had sex with friends
Has she ever cheated on a romantic partner before, whether she says, “Yes, and he absolutely deserved it!”or,“I did, but I was young and immature and I’ve grown tremendously since then,” your response has to be the same: she’s out of the running (unless you want an open relationship).

If the first time she had sex was 22, she was too busy focusing on her studies in college to date, party, or spend an ounce of time on boys, her first lover was her tutor in school right before she graduated, and she attends religious service regularly, you’re safe not probing any further, usually.
If, on the other hand, she first had sex at 15, though only because her boyfriend was pressuring her; many of the men she’s been with since then were friends of hers; loves parties and dancing and drinking; and yes, she’s cheated before, but she’s grown a lot since then, you’ve got some cause to be concerned.
