Reunion sex with hubby... freaking out!!

Sarah

So my husband has been gone for work for over a month (military, TDY in Vegas). He's coming home Saturday, and obviously we'll be having sex. Unless my period decides to arrive. Lately I've been on some new medications that lower my sex drive and make it hard to get wet. Normally, I could have sex several times a day every day of the week (and I wanted it that much too!). This past month, I haven't felt horny AT ALL. So now I'm freaking out because my brain wants to have sex with my man but my body's not cooperating! And it's gonna be really awkward and embarrassing if I'm totally not feeling it Saturday. My husband knows about the problem and he's super sweet about it but I don't know what to do. Anybody else dealt with this and how did you handle it? Any tips for making my sex drive cooperate? And yes, I have lube. Bottles and bottles of lube.
