Good morning.
"I love your blog. You help a lot of people. Now I guess I need some. My younger brother was born with Achondroplasia only in his arms, which means they are very short. He can't dress or undress cuz he can't reach passed his abs. which means he needs help to pee and stuff and needs help showering. Our dad always helped with those things but he died last month. Our mom freaked out when he got a boner in the shower and now he wants to come live with me. I thought he should stay with our mom but he says he can't. He would get hard when dad washed him in the shower but he never said nothing about it. So now I need to figure things out how to help him. Any ideas would be really appreciated."
According to the National Health Institute:
"Achondroplasia is the most common form of short-limb dwarfism. It is an autosomal dominant disorder caused by a mutation in the gene that creates the cells (fibroblasts) which convert cartilage to bone. This means, if the gene is passed on by one parent, the child will have achondroplasia. However, over 80% of individuals born with this disorder are born to parents who do not have the disorder. It affects mainly the long bones. As a result, individuals who have achondroplasia have short limbs but normal trunk height and head size."
In other words, outside of the shortened limbs, everything else is normal ---- including sexual development and function. Difficulties with normal living can include:
If you are not in a position to take him in and help him with those things, I'd say your brother needs his doctor to have a frank discussion with your mom. She needs to understand that his boners have nothing to do with her - they are nothing more than a physiological reaction. Beyond that, you could suggest a part-time caregiver who won't be bothered by the erections.
We often don't think people with physical limitations have sexual needs, but they do. So, on a more personal level, talk to your brother about masturbation. Has he figured out how to thrust into a mattress or pillow and clean up after himself? Maybe get him something he can thrust into, like a FleshJack. Because if he can masturbate and cum, it might lower the chance his cock will get hard when being soaped up in the shower.
