I am male and I do spend a lot of time thinking about sex. It also affects the way I interact with women as opposed to how I interact with men.

It's just like hunger. When I'm hungry, it's hard to think about things other than food. If I'm talking to someone while hungry, and they have food, it's really hard to focus on the conversation at hand. Worse yet, I will often ask them if I can "get a piece of that".
