Unfortunately I run into this a lot. If we're still vertical, I'll make my desires known by hugging her and nibbling on her neck in a playful way - sometimes I'll start early in the day (weekends) with little touches and pats, then let it build through the afternoon to grabbing her around the waist from behind and whispering in her ear - nipping, kissing, etc - by the time evening comes she pretty much knows what I'm interested in - and unless she's really not feeling well - she'll agree to let me give her a few orgasms!

If we're horizontal - I'll give her a back rub, that will generally turn into a more intimate massage.

The key is she knows that I put her first - she's going to get off 2-3 times, so what's not to like?

Usually we talk (or text if he is at work) in innuendo to each other. Playful grabbing, touching and kissing coupled with the talking dirty usually is all we need. If he is really tired then I have resorted to touching myself while he watches to get him interested. Whatever works!
