Changes in vagina

So I'm a little embarrassed but thought you ladies are the best people to ask this question to. I'm currently 27 weeks 6 days with my second. I have noticed that sex feels very very different than before (even very different than when I was pregnant with my first). I actually am really hating sex right now, it's like my vagina has gotten huge and I can't even feel my husband!!? He says it doesn't feel different to him but I think he's lying, it's seriously like that expression, "throwing a pickle down a hallway".... What the eff is up with my lady canal!????!??
