In the framework of a constructionist approach, a life-course point of view
and traditional concepts borrowed from identity theory the authors report
on a study of fifty-six San Francisco bisexuals. The data show that by midl
ife, changing life commitments among the participants were associated with
a decrease in sexual involvement, a move toward sexual activity with just o
ne sex, a decrease in contact with the bisexual subculture, and a decrease
in the salience of a bisexual identity. Given these changes, the data revea
l the opposite of what might be expected-an increase rather than a decrease
in the certainty about and stability of the bisexual identity. The authors
show that this was due to the continuation of dual attractions that were p
ositively regarded even as there was a move away from a bisexual lifestyle.
In explaining these findings, they discuss the interplay between sexual co
mmunities, relationships, selves, and sexuality.
