The decision of when to have sex (and with whom) is a very personal one. Some stars make the choice to abstain up until the wedding night, though, and that list of self-proclaimed celebrity virgins is longer than you might think! Jessica Simpson famously vowed not to do the deed until she said “I do.” The former Newlyweds star stuck to that promise and was intimate with Nick Lachey only once they were man and wife in October 2002. She was 22. Adriana Lima also swore off sex until her wedding night, telling GQ in 2006 that “sex is just for after marriage.” Of course, you can’t forget 19 Kids and Counting star Jill Duggar and her hubby Derick Dillard. The conservative Christian pair didn’t even kiss until their June 21, 2014, wedding. That night, they, um, consummated their union.
