As the above poster said, I think it is strength (physical and emotional) that differentiates men from women.

I'm physically strong, but emotionally weak thanks to my BPD (which is why I have zero luck with women). I've given up on women, and moved on to the gym and weights

There's nothing like that feeling of the testosterone surging through your body when lifting weights and seeing those delts and arms and pecs swollen big pumped with blood ... and that, my friend, is why I love being a man
