Can having sex everyday affect the chances of conceiving?

Me and my boyfriend have been trying since March I'm 20 he's 22. We would have sex like everyday or every other day. I told him to just slow it down a little and just do it 2 or 3 times a week cause I'm starting to think that's why I'm not getting pregnant I guess because we're having to much sex. Can it affect the sperm count by doing it every day in a week or it doesn't matter?
