One in ten Individuals have used an internet dating web site or cellular courting app themselves, and many individuals now know another person who makes use of on-line relationship or who has discovered a partner or lengthy-time period companion via on-line relationship. We investigate whether a range of courting and sexual experiences throughout adolescence affect younger adult outcomes. We assess whether the numbers of relationship companions, sexual companions (relationship and casual), casual sexual companions, as well as relationship churning, and sexual nonexclusivity amongst 18-19-year-olds (in 2006) influence 5 indicators of well-being measured 5 years later (in 2011). From a conventional risk framework, we anticipate that extra relationship and sexual companions signify relationship baggageâ€ and can detrimentally have an effect on properly-being. Moreover, we move beyond prior work and think about how the specific nature of sexual partnershipsâ€”relationship and casual, relationship churning, and sexual nonexclusivityâ€”influences younger adults’ nicely-being. We discover how these more nuanced indicators may be associated with younger adults’ properly-being.
