Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are now allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will continue be removed and our normal comment rules still apply to other comments.

Nineteen studies in total were aggregated and analyzed. The results showed that the pupils of heterosexual men dilate much more when viewing stimulating images of women rather than men. The pupils of gay men, on the other hand, dilated more when viewing men compared to women. These results clearly support the hypothesis.

The picture was less clear for women, however. The pupils of heterosexual women did dilate more when viewing heterosexual imagery, but the difference was not statistically significant. Aggregated studies examining lesbian women actually found that their pupils dilated much more when looking at heterosexual imagery, but the authors caution that this result likely can't be trusted on account of an overall small sample size for lesbian women and because one outlier study completely altered the directi of the link

Can't wait for a Google Glass app that detects this comes out. Women will be accusing men of sexual harassment for the way men's bodies involuntarily react.
