Won't stay wet

Be

What the hell is going on? I'm insanely attracted to my husband. He touches all of the right spots with all of the right tools, and never fails to make me orgasm. BUT, if I do get wet, I do not stay wet. Most of the time I'm not getting wet at all. I'm totally aroused, but it's like... it just won't turn on. We still have sex multiple times a day, but he says it is starting to wreak havoc on his ego. I hate that. I love him, and he totally does it for me. Yes, we've started using quite a bit of lube, but I won't to just get wet like I used to! There is tons of foreplay, I'm always well hydrated, decent diet... nothing has changed. Well, other than the string of miscarriages since May. Is that it? Are my hormones out of whack? Help!
