Please help ladies !

Hey guys so this community has been sooo comforting lot me always so I thought why not ask you guys about this since it stresses me out a bit. Back story my husband just turned 40 and I’m 28. We have a baby girl who’s a year and half and I just found out I’m pregnant again. I don’t know the gender yet but of course iv always wanted to experience a boy and a girl so hoping for a boy. I was reading online and I saw something that said older men are more likely to have girl vs younger men ?? What’s your guys experience ? I would love to hear your thoughts.
