RESUMO
This study compared public versus private affection-sharing experiences of individuals in mixed-sex (N = 1018), same-sex (N = 561), and gender-diverse (N = 96) relationships. Private affection-sharing was similar across groups, except those in mixed-sex relationships reported somewhat less comfort doing so. Despite having a stronger desire to engage in public affection-sharing, those in same-sex and gender-diverse relationships shared public affection less frequently, were less comfortable doing so, refrained from doing so more often, and experienced much higher levels of vigilance related to public affection-sharing, compared to those in mixed-sex relationships. Heightened PDA-related vigilance may have health consequences, as higher levels were associated with worse psychological and physical well-being in all groups. However, individuals in same-sex relationships showed weaker associations between vigilance and well-being than those in mixed-sex relationships, suggesting possible resilience. Still, engaging in vigilance may take its toll, potentially serving as a mechanism through which minority stress works its effects. When we controlled for PDA-related vigilance, psychological and physical well-being levels in same-sex relationships increased relative to mixed-sex peers.
