The wife has the baby on her mind and can't relax, and then the husband then gets turned off by her attitude. Some people need to be in just the right state of mind or they can't make love. Some people need the excitement of illicit love. Everyone is different.
有些夫妻本來好端端的，生了孩子後忽然不行了，原來是太太惦著孩子，放不開，連帶弄得老公性趣全無；有人一定要心無掛慮才能做愛，有些人又偏喜偷情刺激，真是人人不同，各有所好。
