Here's a newsflash for you - men are just as needy as women. They feel every bit as insecure, and they need to feel wanted as much as you do. We already know that they take pride in their masculinity, and they love to feel like 'real' macho men. So, get their attention by making them feel that way.
Deep down in their DNA, men are still hunter-gatherers and want to be seen as your protector. So, ask them for help and assistance - get them to do some housework for you, ask them to walk you home. Get them carrying your bags and convince them you need them to do it and only they can help you. They bask in it, and it gives them a chance to feel valued and useful to you. If they feel like you need them, they'll always make themselves available.
