Tmi question.!

The question can sperm (meaning hubby cumming inside you) cause ur cervix to thin. And cause a miscarriage.? 

I think yes! Because I've always read that at the end of ur pregnancy sperm can thin the cervix and help

Labor start. If that's true then why wouldn't that be a worry during pregnancy? He thinks it's false and that sperm is totally save and of course he's a guy and wants to saw sperm is even good for a women's health (including swallowing) lol 

Your thoughts ladies!
