Ok I have a clearer pic now. My H also snores (to wake the dead) at times and the other things you mentioned (minues leg tremors. But one steadfast rule we have is that we go to bed at the same time.
Occasionally one of us has to move to the couch to sleep soundly, but we always (ALWAYS) start off together in bed. As you know there is absolutlely no chance of you two getting physical with you in separate rooms. Also, the way you phrased this ("I would not get him up any earlier than his usual 5:15- if I valued my safety!") makes me think....he isn't going to bed early enough anyway for him to get enough sleep if waking him up a bit early for some nookie would make him cranky. Perhaps he's a nightowl, I am naturally...and certainly used to be prior to my R w/my H. Now though, we head to bed at the same time ALWAYS...sure sometimes one of us stays awake and watches tv every now and then, which is fine....but at least we have the opportunity to snuggle, and snuggling can lead to other things.
I really encourage you to try to instill a time for you two to go to bed together. Perhaps you could compromise and make it around 10:30, that way you aren't staying up too late, and he won't feel he's having to go to bed extremely early either.
