If he loves you, forever. Do you HAVE to have sex at that time of day? Maybe you could do it between breakfast and lunch on the weekends or whenever neither of you two are at work? I know how you feel though. I'm the same and once I got put on anti depressants the old sex drive took a long holiday and has yet to come back. Luckily hubby puts up with it (loudly, but he puts up with it).
