Sex since finding out about pregnancy

So I am 7weeks, 3days pregnant and we have only had sex one time since finding out. My husband works a lot and I am always tired, but still find myself wanting it so much more this pregnancy then my last pregnancy. Also was a little nervous to have sex, but I feel better now since we have already done it once. Does gender have anything to do with wanting sex more or less? With my daughter I didn't even want my husband to touch me. This pregnancy is so different then my last, it is crazy. Have any of you ladies done it more or less since finding out about being pregnant? If not first pregnancy is this pregnancy different then your other ones?
