Diversity in human sexuality

Socio-behavioural research demonstrates unequivocally that both heterosexual and homosexual men feel that they have/had no choice in terms of their sexual attraction. The majority of women who experience same-sex attraction also express a lack of a sense of choice in their sexual orientation, although there is evidence for much greater fluidity in sexual orientation among women of all sexual orientations.
The study explores – and finds lacking – evidence to support the contention that the way parents bring up their children, or the relationships formed between children and parents, impact on sexual orientation. While family environment may shape other elements of sexuality and the way sexuality is expressed, and while construction of gender and sexual identities have strong social and cultural components, there is little evidence that orientation is directly correlated to family upbringing.
This report explores but could fi nd no evidence that sexual orientation can be acquired through contact with LGBTI persons. Instead, the panel found substantial evidence that tolerance of same-sex orientation not only benefi ted LGBTI persons but impacted positively on public health, civil society and long-term economic growth in societies across the spectrum of economic development. ‘Peer pressure’, although a powerful influencer of young people’s behaviour, has not been shown to influence same-sex activity or the development of same-sex sexual or bisexual orientations.
