I'm going to focus on the positive things rather than the things I wish my husband would do to show me that he loves me:

Things that my husband does that I really appreciate:
- at random times, such as when I walk in the door after work or just came back from a bike ride, he tells me I look 'great!' (I like that so much better than 'beautiful' or 'hot' or things like that -- 'great' sounds more sincere to me for some reason)

- he makes me tea

- if I'm working late (at home), he'll make me dinner without asking, and bring it to me

- he is really REALLY nice to my friends - I love that about him

- when we're doing something that is easy for him but harder for me (sports, usually), he is incredibly supportive and really makes me feel like I'm doing a good job

- he hugs me a lot

- he always looks really happy and says what a good 'cat mom' I am, whenever I take care of them in some way (clip their nails, brush them, wash their bowls... whatever -- he always appreciates it)

- he brings me flowers (even better, plants sometimes) when he knows I'm feeling down about something. One time he bought me a really sweet coffee mug (I know... sounds mundane, but it was hip and cute) with a chocolate bar. He really is a sweet guy.

- when he gets ice cream or some kind of dessert for himself, he always gets some for me, too (even though I feel like I don't deserve it)

... so, they are simple, random things that mean a lot to me. Those are the tips I would give men.
