To much or not enough sex?

Ashley

So I have a question. Me and my man have been trying to conceive and I always here two different sides to the story. So first I was told if you have sex a lot that the sperm count won’t be as good and higher chance of pregnancy Then if I wait a day ? Is that a wise tell? I also heard if you don’t have sex for a week and then have sex that that sperm won’t do anything because well it’s not as potent?? Or higher count. What’s the real truth
