Totally know what you're talking about
. It was my husband's birthday last night and I had all the right intentions. Except, I over did it the past few days and basically crawled in the door after dinner feeling horrible! I just kept apologizing to him, but I just needed my bed. Today I'm still hurting horribly and we had to run so many errands and prepare for his 30th birthday/super bowl party tomorrow so I'm not quite sure he'll be getting anything any time soon
Evey, I'm so with you on the being young thing. My husband and I have been married a little over a year and you certainly would not know from the amount of sex. Thankfully he is so patient and understanding. The other week I had an urge twice in one week, he was in heaven 
He keeps telling me that he can't wait until we start trying to get pregnant because he knows he'll get it all the time!
The joke of the woman always saying she has a headache is a sad reality for us, except the excuse changes every night but is very real each and every night!
