tmi subject. partner not going 'down there' when your pregnant.. anyone else?

So I'm 32 weeks pregnant now and hubby hasn't 'been down there' since before I fell pregnant. It doesn't bother me, I mean I feel disgusting anyway but I was just wondering if anyone else's partner is the same? And if so do you know why? I'm trying to work out if he just isn't into me anymore or if it's the pregnancy that's a put off? We have sex but foreplay isn't really a thing anymore , not oral anyway.. I hope I'm not the only one??
