Husband too grossed out to check if civix is open

So I'm 34 weeks pregnant and I've been having sharp pains in my vigina for the last hour and if I try to put my legs together the pain gets worse  and if I walk I can feel sharp pains. I've been laying down for half an hour and I have to lay with my legs kinda spread open. I tried to pay on my side with a pillow but it hurts.. Anyways I looked it up to see if it's common and people sayer check to see if I'm dialates because it's a sign of premature labor. So I asked my husband to check and he was grossed out by it and didn't want to do it😂 I was shocked because if it was for sexual purposes he would have dropped everything and wouldn't even hesitate but if it was for medical purposes he gets grossed out.  is it only my hubby that's weird like that? 
UPDATE: if he was willing to check we would use gloves to avoid infections I'm a nurse I have hundreds in the house. 
It's our second baby he was ok with checking the first pregnancy but after he watched the baby being born he is grossed out with any vagina related medical stuff.. And leaking boobs gross him out too haha.
