Lolo Jones is an Olympic track and field star gunning for gold at the London Games this summer. But you know what's really hard for Jones? Keeping her virginity intact for her future husband, whoever he may be.

On HBO's Real Sports with Bryant Gumbel, Jones talked about her struggles:

It's just something, a gift that I want to give to my husband. But please understand this journey has been hard. If there are virgins out there, I just want to let them know, the hardest thing I've ever done in my life—harder than training for the Olympics, harder than graduating from college—has been to stay a virgin before marriage.

Jones adds, "I've been tempted. I've had guys tell me, they're like, 'Hey you know if you have sex it will help you run faster.'" She joked that her response has been: "If you marry me, then yeah."
