I agreed with mae.. sex is not the only way to show your love and solve the problem.
There are many ways to show your love beside sex..
If having sex can solve all the problems about love, then we wont have so high divorced rate in singapore, about 20 cases a day.
Moreover, Making Love can be fake also.. some man do visualise about having sex with another woman while making love with their wife.
How to make marriage work when you dont feel love anymore??
My ans is very simple... if there is no love anymore, y still want to make the marriage work?
If there is still love, both parties shld sit down together and tell each other how you feel and how to find ways to make Love grow.. and not let it fade.
