Demon cervix??

My sex Drive is absolutely nil (17 weeks pregnant). Myself and my partner used to have sex very regularly. Last night, I thought I’d make an effort considering it was Valentine’s Day.

He did not last long. Literally under two minutes 😑. Afterwards - now, he never shares anything like this with me - he said it was like the “top” of my vagina scratched him just as you would like you would use finger nails. I assume he’s talking about my cervix. He said he was then tingling but it wasn’t unpleasant. What’s going on??
