You, my dear, were the topic of choice in the frozen north 'cuddle puddle' last night. Two thoughts:

First, that old chestnut sprung to mind. "If you think you are _______, then you probably aren't." It works for for 'loosey-goosey' as well as 'crazy'. So put that thought right out of your mind.

Second, it's really hard to stomach the thought that you (both) can be in your 50s and not be comfortable with what you want. Where's the harm? I think if you gave him a kiss, and said plainly something like: "Listen, I like you. I think you can make me happy. I think I can make you happy. Last person to the bedroom has to cook breakfast." and then ran like the omlette monster itself was after you, you'd be just fine.

Whatever path you choose, we wish you the best.
