Dear professional, in my house I have two autistic sons aged 8 and 12 years old. The eldest son is already fully into puberty, so that's why he practices a lot with sexuality! in addition, his younger brother looks up to his older brother very much, so he takes over all sexual behavior! both sons have also been processed via artificial insemination via donor sperm, which means that they are very busy donating their sperm later in the future. They do that by lying in their bedroom masturbating in their nudity at a certain time! this behavior started with my oldest son, but not much later he taught it to his younger brother too! my question to you is: is it normal for my oldest son to excite his younger brother about things like sexuality, especially things like having kids and masturbating?
