Being a middle school teacher there are obviously a lot of hormones going on and bodies changing etc. I know personally I deal with mostly males that have Autism, so I can only speak from the male side. I have parents of students with Autism that come to me and tell me how John Doe has finally wore jeans instead of sweatpants to school because he like Jane Doe. Now the mother and myself have tried for years for John not to wear sweatpants, but all it took was one love interest and the student is more conscious of what he or she is wearing, thus making a huge step in becoming more mainstreamed.
Then I have other parents that come to me and tell me that their child likes another student, but has no idea how to help the student in establishing a relationship, when the student clams up when speaking to the oposite sex. I tell the parents that many times to have the student start with Facebook or twitter and just talk to the opposite sex on their to help calm the nerves, thus gradually introducing them to talking to the opposite sex.
These are the types of things we need to look out for as parents, teachers and friends of those with Autism to try and push them to have more self confidence. The more confidence the student has the more mainstreamed they become.
As always please leave feedback and suggestions for any future post.
