It goes both ways Freya. And the issue isn't about women desiring support from their partner. That's a given. The issue that men are taking is how the women in their lives have chosen to communicate that need, and the definition of need versus giving sex for a 24/7 handyman.
Feel free to get offended if some of this hits home a little too closely for your comfort - that's your choice. And nobody likes to be told that they're "doing it wrong."
Sometimes, a man might like to relax, not talk, clear his mind or meditate for a while. However, some women will abuse offered support. Even though she has her own computer, an iPhone and an MBA, my girlfriend will often ask me to look things up on the web for her, help her make basic scheduling decisions (my root canal is killing me, when should I see the dentist?), help her find out the weather report, help her find her phone. These are all things that she would do, without any fuss if I wasn't around - but because I'm there, I get to do it.
