TMI! Advice needed!! Have you ever had issues getting wet?

My daughter is 2 and half and my last pregnancy that ended in miscarriage at 11 weeks was 1 year ago. I was on the Skyla IUD for 7 months and then got it out in April and now I am no longer on any birth control, because we are trying to conceive. I am not on any medication or anything. My period ended 3 days ago and was normal.. Okay so now you know the basics.. The last two times my husband and I have tried to have sex I cannot get wet. We tried last night for a while, he fingered me and tried to get me wet for awhile and it just wasn't happening, he finally said "Well babe I guess it just isn't happening tonight".. It's so weird because I have never had this problem before. My sex drive has been really bad lately too. It's not like I am not attracted to my husband I just haven't been in the mood lately. He was kissing my neck the last time we had sex which I use to love and I just wanted him to stop.. Has anyone ever experienced anything like this??
