Let's be honest -- anyone who has ever been in a relationship has probably thought about doing a little snooping, whether it's a sneak peak at an S.O.'s email or a casual glance through his or her texts.
However, according to a new survey, more people than you think are actually doing it.
Avast -- an anti-virus software company -- asked 9,202 men and women in committed relationships whether or not they secretly check their partner's smart phone, and nearly one in five men and one in four women said "yes".
The motives, however, varied by gender.
The number one reason men said they snooped (26 percent) was because they suspected their partner was cheating on them. Another 24 percent said they did it because they are simply nosey and 12 percent said they wanted to catch their S.O. in a lie.
Women on the other hand, were motivated more by curiosity; 30 percent said they snooped because they are nosey, only 21 percent suspected their S.O. was cheating and 14 percent wanted to catch their S.O. in a lie.
For many, the risk was worth the reward: 71 percent of women and 53 percent of men said they found evidence of cheating or lying by checking their S.O.'s phone.
Obtaining access wasn't exactly hard either -- 41 percent of women and 33 percent of men said their S.O.'s phone was not password protected.
