There are significant facial shape differences between homosexual and heterosexual men, scientists have claimed.

The results showed that homosexual men were rated as more stereotypically 'masculine' than heterosexual men, which undermined stereotypical notions of gay men as more feminine looking.
Researchers also asserted that homosexual men showed relatively wider and shorter faces, with smaller and shorter noses, and rather massive and more rounded jaws, "resulting in a mosaic of both feminine and masculine features".
