text: You could have a health issue.  Maybe talk to your doctor.  Are you depressed?  Do you have sleep apnea?  Do you have diabetes?  Low iron? Pregnant? If you aren't married, already.. go out and find someone that you find very attractive.  If you are married, already... ask your partner if you can both liven things up a little bit and try something new.  Nothing like a new adventure when the lights go out!  :)
