Too much sex?

Tanya
Hi guys, 
​So my boyfriend and I usually have second every day, and when we have days off at the same day it could be more than once. I heard so many times than the best is to have sex every other day because of the sperm quality. I just don't know how to say to my boyfriend hey we can have sex every dAy, unless is really lowering my chances . Any advice ladies? Thanks and I've been trying for 2 months! ;)
