So when boys want to wear tank tops, it’s okay, but when
I want to do it, it’s indecent and my shoulders are going to
give every boy in a 20-mile radius a boner?

if your underage and its a professional environment, wear
professional clothing. women have sexual organs on their
top half, men don’t, don’t you know biology??

breasts aren’t sexual organs and neither are shoulders
do everyone a favor staple your hands to your ass

I get what you’re going for here but breasts are very much a sexual organ in many ways and saying otherwise is bad science. As everyone with boobs has probably realized at one point or another in their lives, on average they shouldn’t be nearly as big as they are. Looking at other mammals you’ll notice most of them have significantly less fat deposits in the chest area. No one is quite sure of the specifics but it’s generally agreed that for one reason or another humans evolved to have bigger breasts, and one of the biggest possible reasons for that is to attract mates, since being able to support a well rounded figure suggests health, or at the very least a lack of malnutrition. Most people who are attracted to women, male, female, or what have you, find breasts to be visually pleasing and interesting, they’ve acted as a focus of desire for thousands of years and while that’s a little strange when you think about it logically it is very much part and parcel of attraction. Plus there are way more nerve endings in there then there should be if they were only for nursing, it is technically an erogenous zone that the majority of women can derive pleasure from. While not their first purpose breasts have evolved to be major element of sexual attraction. 

Of course you could make a similar, if weaker, argument about men’s chests and we don’t cover those up, and shoulders regardless of gender definitely aren’t censor worthy. Still, a common pair of tatas has design features for things other than baby feeding. 

swimmin what do you think of the whole nature v nurture thing? are boys and girls really different (brain-wise) or is that difference caused by social interactions? pls i wanna know your thoughts on this

swimminindafists:

Well males and females and non-binary people definitively have dimorphic brain structures starting in the womb, as a result of the hormone baths they’re subjected to. Unless there’s a secret society of oppressive patriarchs born like fungus out of amniotic fluid in mother’s bellies, socialisation can’t explain foetal brain differences, not when they start before any social interaction occurs. This explains why boys and girls show different interests starting from birth, with boys more interested in structures and building stuff, and girls showing more interest in interpersonal relations and faces, hence dolls. There was a study that found female chimpanzees had the same interest in dolls as human female infants, and hormones affect brain structures in foetuses throughout the animal kingdom. It doesn’t make sense that in 60000 years of human evolution, sexual dimorphism and evolution would produce sex differences in the bodies of humans, but not in the brain, the feedback centre for the entire body. 

But all that is just like the first chapter in people’s identity. It’s nothing to get hung up on because humans are evolved enough cognitively to override that kind of biology, and there’s enough variation in hormones and brains for there to be plenty of outliers. Plus, things like careers and science are subjects wayy beyond what our brains and bodies were built to consider, so after an early point, it’s more evolved issues of choice and hard work at play; it becomes more about what we fill ourselves with than what we were pre-filled with in the packaging. Plus, what we actually accomplish isn’t just a linear reflection of the brain; it’s based on actions and choices. Boys can be just as empathetic and interpersonally successful as girls, and girls can be just as technically proficient and scientifically trailblazing as boys, and everyone has the potential to be a trashy mime with a resume of bar mitzvahs a mile long. Another example is it makes more sense reproductively for humans to be non-monogamous, and people’s sex drives are built for it, but out of choice many people have very successful monogamous relationships. Basically, people can choose to be who they want in the end, but sexual dimorphism in the brain is real, and explains certain correlations in interests.
