Fellow mommies I need some advice!

Its a little personal, so bear with me. ☺

So, with this pregnancy I have been having a very difficult time getting wet/lubricated when trying to be intimate with my fiancé which never happened to me before I became pregnant. Also, of course he is a little upset and thinks I'm not physically attracted to him anymore because of this little issue, which definitely isn't the problem! So pretty much what I would like to know is if any of you other mommies have had this issue during your pregnancy?! Is it normal?! Is there anything I can do about it?!
