" Unless an individual is early in their partnered sexual life, having no past partners is stigmatized too. A large nationally representative U.S. sample of single adults found that participants were generally unlikely to consider establishing a relationship with a "virgin." Sexually inexperienced individuals were rated less attractive than were those with some experience (Gesselman et al., 2016).

In fact, those who were themselves sexually inexperienced themselves were especially reluctant to connect with someone inexperienced! Sexual inexperience in adolescence and young adulthood is not necessarily perceived negatively, but once one leaves that life phase without having gained some sexual partnered experience, there is a risk of being perceived as non-normative."
