Hi april, yes, I go through stages of no sex drive. If you know in advance that you have a night (or afternoon

) with just the two of you, prepare yourself. Don't do anything to cause a flare-up the day before. Just pamper yourself. Take a nice long hot bath. Take a long nap. Then that day, or night, calm your mind and forget about your symptoms for the day (hard to do I know).
You just really, really need to put the relationship first on this day. No talk of symptoms, no yawning

, and get a baby sitter if you can!!
And if you have a big bathtub, or a hot tub (which I do not

that would be great for the both of you!!
