Are you ever too Sleepy?

I find it hard sometimes to have sex in the middle of the week... but this also scares me. I am in my mid 20s and too tired. I dont have children, but I do have two dogs...so.. but by the time I get home from work... make a yummy dinner for both of us, wash the dishes, clean up... etc... Im a little tired... I tend to find myself in a shower with a vibrator to wake myself up and get me in the mood... sometimes I actually get off, which is a big no no... I want to be able to please him..and if I get off, and im tired already... Im only going to pass out...

Is this a common issue for people? I am assuming it is.... too tired from working all day to actually get involved in the act of fucking.... I dont mind laying there and getting eaten out... but... I like to be in charge and really take charge in sex... I try to show him up basically ... hahaha....

If you have any suggestions in staying awake after work.... let me know.  ;-)
Maybe its just the weather... it has been gloomy lately... that usually makes me a sleepy bear... ;-)
