Hey cogoli!
I know how you feel, cuz I am in the same boat. Sex seems like such an effort now that we are actively ttc.
I was told by someone, and I thought i'd pass this on to you. You may need a change of setting, so like going away on vacation, for a week (when you know it's ovulation time) and relaxing, getting away from it all. It seems like having sex isn't as much of a "chore" when you are away from the everyday, and it might be just what you need for you to actually conceive.
My hubby and I are going away for 10 days in april.
I hope this helps! ;-) good luck!
