pubmed-article:7560939 | pubmed:abstractText | Current research into possible biological bases of sexual preference has failed to produce any conclusive evidence. These studies omit the influence of psychological and sociological factors on sexual expression. They conflate the individual with his or her behavior. An argument against the dichotomization of sexual expression on the basis of the individual's biological sex or that of his or her partners concludes this paper. | lld:pubmed |
