Too much sex a thing??

I've read many articles about TTC but I'm getting confused.. some say do it as much as you want whereas others say only every other. The articles that make it seem like there is no such thing as "too much" accredit this to allowing constant new sperm to release and not allowing a build up of Sperm which gets "old and slow" that way they reach your egg faster and easier.

But then the other articles say that doing it too often can inhibit the man from releasing enough sperm. Can anybody clarify this?? Been BD'ing every day for like a week and a half straight during fertile time for the past couple months. So I'm really not sure if we should try doing it less????
