My husband won't have sex with me..

He tries to, but then he will start panicking thinking he's going to hurt the baby.. I'm almost 38 weeks and he says if the midwifes fingers can touch babys head then his penis certainly does too, and a 2cm thick cervix isn't thick enough for him not to feel it.. he's also saying that it must rock his world as well, having all these sudden jerky movements.. he will constantly ask if baby is ok during sex.. then he will go soft as he overthinks it..

I have explained it's not at all harmful to the baby, and that actually, sex is reccomended at this stage to get things moving and potentially put me in labour!

What can I do to get his mind off of the baby!! I've tried so many things like kissing him, talking dirty, different positions so the belly is not so "in your face".. any other suggestions??

EDIT: I would reply individually but there's no way to remain anonymous in a reply which defeats the purpose of posting anonymously.. he WANTS sex, he wouldn't come looking for it if he didn't.. but it's during sex that he starts overthinking it.. the replies so far have almost made it seem like this is something I am forcing him to do which is not the case at all. We both respect each others boundaries and I wouldn't ever try to make him do something he doesn't want to do..
