Although many self-identified bisexual individuals report having at least one child, bisexual parents' unique experiences, including sexuality-related communication with their children, have been largely absent from the parenting literature. We conducted in-depth interviews via telephone (or digital telephony such as voice over Internet protocol) with 33 individuals who self-identified as bisexual were at least 18 years old, had at least one child (genetic, adopted, step, foster, guardian or partner's child) and currently living in the USA. Nearly all participants encouraged their children to be tolerant of sexual and gender diversity. Sexual behaviours were primarily discussed in terms of protection from sexually transmitted infections and unintended pregnancy. Participants' approaches to communication included non-verbal methods (e.g. role modelling) and pragmatic verbal discussion. Participants employed numerous strategies, including age-appropriate, child-driven and opportunistic discussions. Some parents did not discuss sexuality at all with their children. Many had not received training in childhood development or sexuality education. The participants' experiences were often similar to previous research on parents of other sexual identities. However, due to the unique stigma associated with bisexuality, findings point to a need for developing and providing targeted resources for bisexual parents to assist in discussions about sexuality within the family context.
