I wonder if there is any correlation statistically between being the eldest sibling and being a boylover? The eldest sibling with no father-figure might be more prone than younger siblings for whom older brothers can become 'replacements'

Interesting idea! It kinda fits my situation: I am the eldest, single, and a BL ... while my brother, who is 5 years younger than me, is an extremely well-rounded, happily-married husband and father.
