It keeps us preoccupied with things that are not positively associated with mutuality. In couples where one party loses hearing after the bond is formed, their sexual relationship can be affected the most. In many cases, good relationships have not developed. While hearing loss hasn't caused the problem, it makes the problem more insoluble. Timing in relationships is very important.
Sex often depends upon the right time and the right atmosphere.
A hearing impaired person often misses or cannot understand romantic cues. Each couple develops its own sense of mood, of energy and spontaneity. Some like each step in the process planned. Each bond has its own sense of timing, but in the person who is hearing impaired, the sense of timing is thrown off. Spontaneity gets lost.
