SPERM COUNT

Oka so I have a question..me and my partner have been having sex twice a day since I've started my ovulation cycle. it's not over yet and i don't want to stop but I've heard that having sex everyday can shorten the man's sperm count. Is this true? Since I got a little worried I told him we are not going to have sex at all tomorrow and we'll just continue on the main ovulation day and perhaps the day after. I swear I didn't think we were doing anything wrong...I HOPE I DIDN'T BLOW MY CHANCES THIS MONTH 😅😔😢..
