Yes a mans body runs with testosterone, but your voice comes from an outside help that is not you.
This "testosterone is natural" crap is such a denial, because obviously there's a difference.
You guys talk tough, but few days in the interrogation room and you would already snitch for any high you can get
But, like aj said, being jacked is fun, so to each its own. But when I'm drunk for example, I tell a woman "I'm drunk, so I will probably see you much hotter than what you really is, because when I'm sober there's no way I would use a public transport to travel 20km just to have sex with you. Just so you know"
