Men and women usually have different hand proportions, index/ring finger ratio in particular (2D:4D). It's been found to be linked to prenatal testosterone levels during early parts of brain development, with low 2D:4D related to higher prenatal testosterone exposure. There are many scientific articles out there (of varying quality) showing statistical links between 2D:4D ratio and male/female behavior patterns.
This might be a little bit sensitive, but I'm going to step aside from political taboo just because I find it interesting. Here are some articles as an example:
A study where feminist women were found to have a more masculine distribution of index/ring finger ratio: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4158978/
Correlation between masculine index/ring ratio and crimes: https://www.researchgate.net/publication/256466184_Criminality_and_the_2D4D_Ratio
Female rowers with more masculine 2D:4D tend to perform better: https://pubmed.ncbi.nlm.nih.gov/25242253/
2D:4D ratio does not predict current levels of testosterone for adult men: https://pubmed.ncbi.nlm.nih.gov/32572079/
Low 2D:4D linked to choice of judo/boxing instead of aerobics: https://www.cambridge.org/core/journals/journal-of-biosocial-science/article/sports-preference-and-digit-ratio-2d4d-among-female-students-in-wroclaw-poland/6AD5C8B045056C2C3AFB3291358B07F4
I thought it would be interesting to create a thread where people can share their perspectives on this. The reason is that I'm affected by it personally - I'm male with a digit ratio of 1.04. I'm not part of any of the sexual minorities, but I often feel "dyslexic" with behavior patterns related to masculinity. During childhood the timing of my growth was much earlier than what's normal for boys, and I can do the "chair challenge" without any effort.
Anyone here who has worked with studying 2D:4D, or someone who has anecdotes about yourself or someone you know?
Things about me: I am super anxious about everything. Which really sucks since men aren't supposed to be anxious, but it is fine after I accepted that I'll die alone. Women aren't attracted to anxious men and it gets even worse that I'd have to overcome my anxiousness probably hundreds of times for anything to ever happen. Just doing it a single time feels like death.
Anyway, there are plenty of fun stuff to do as a loner today so I'm reasonable happy, probably not far from as happy I can be given how overly anxious I am. Being anxious usually doesn't lead to healthy relationships so even if I did go through all that work most likely it would just end up like shit and I'd be way more miserable than now.
I do have a lot of anxiety, I am not muscular but rather skinny fat. I am also attracted to yoga, running, swimming, etc instead of more manly sports like football or even soccer. I do lift weights though. Another funny thing, I tend to really enjoy games in which you play as female character like Tomb Raider and if a game let you pick your gender, I tend to pick female. Outside of video games, I have no desire to dress as a female.
Based on these traits it does seems I have "wrong" ratio.
