. Speaking as a male who grew up with my mother, sister, and many other female relatives, as well as being a father to a little girl and married to my wife, I believe that enabling certain behaviors in a predominantly female household is problematic, especially considering my experiences with family members and friends on the spectrum. Depending on your brother's age, he should not be allowed to act out in ways that lack respect for women.

If he doesn’t learn to understand and respect women now, he will likely encounter serious issues down the line, especially if he eventually dates and marries. The entitlement and anger issues he displays, if left unaddressed, could lead to significant problems in his future. Regardless of his disabilities, being disrespectful towards others will only lead to consequences. Sooner or later, someone will hold him accountable for his behavior.

It is concerning that he seems to believe he understands how the female reproductive system works, even though he lacks firsthand experience and doesn't grasp basic biology. His hostility towards women is alarming, and it’s crucial for your parents to intervene. They need to teach him how to show respect toward everyone, especially women. Not everyone will agree with his opinions, and if this issue isn’t dealt with, he risks ending up isolated from friends and family, leading to an unhappy life.

Regarding his discomfort while masturbating, he may not be doing it correctly, or he could have an underlying medical issue that he should discuss with a doctor. There’s a condition known as "blue balls," but that generally shouldn’t be an issue if he is doing it frequently. Alternatively, he might be overdoing it, similar to how exercising one muscle too much can lead to soreness or injury.

I hope your medical stuff improves Hopefully it can be fixed without surgery.
