The MAXIMUM time would be when the baby comes out but I think you mean the MINIMUM time. Which is 2 weeks after sex. That is the earliest the test is positive. If you mean when it starts to show it's usually not until second trimester.

Too much sex is too much good. Too much sex happens around the time of marriage, when partners meet after some separation for some time. Too much sex happens in extramarital affairs. Other times most people do not have too much sex because there is no too much excitement after novelty wears off. (Sexual addiction is rare and controversial.)
There is no maximum age to enjoy sex. As long as 2 people don't have too many physical limitations, they can enjoy sex.
