To have a good sex life in your marriage, I will list about 5 things

1. Sex should last no more four minutes. If sex last more than four minutes than, it could increase chances of a stroke.
2. Oral sex should not last longer than five seconds because oral sex is nasty and only for porn stars.
3. Foreplay is too erotic and could make you neglect your real responsibilities so tongue kissing should not be allowed.
4.  Sex should only take place when in the bedroom with the doors locked. It should not take place no where else.
5. Never and I mean never wake your spouse up with oral sex. This will lead to a divorce.
