It wasn't just that they wanted to be around them. It seemed to be particularly relevant to the sexual interaction, the stimulation they would receive.

My caution in terms of directly applying the caffeine or the coffee before sex to enhance your sexual drive or motivation would be that in this experiment, we gave only one dose of caffeine to animals who had never had caffeine before.

There are a lot of women out there with sexual dysfunction, and if they understood how that happens or how we can augment that, that would be a helpful thing.

The female seems to control the mating encounter.

The way we measure their interest is they go back and revisit the male after they've just had some sexual interaction with them.

(What she meant was fencing is relevant) because of the moment-to-moment interaction of two actors together who have to be listening and aware of each other, and who have to be so completely involved in what's going on in the moment that everything else sort of becomes secondary. It's the focus, the one-on-one interaction, the moment-to-moment.
