If things are not done the way the parent wants and they become angry then the child may learn to fear the parent and pull away from them.Oftentimes aspies feel most relaxed and comfortable when they operate within fixed routines.
Difficulty understanding social cues may also make communicating somewhat challenging for those with asperger syndrome.
Finding it hard to understand facial expresses or to read between the lines with what others say or do can also make relationship building a challenge.
Or it may also be that they simply do not know how to relate intimately with another person.
If social interaction is difficult then being physically intimate can take this difficulty to a whole new level!
Parenting is not an easy task at the best of times.
