Humans are weaker still and, without tools, lose in fights with the smaller but stronger Chimp or Orangutan.

Without tools? I have just one word for you: Bruce Lee. Okay, that's two words...

Seriously, you do have a point. Grouping (no, not groupies) is a survival tactic and, obviously, a very successful one.

A question, though: How is it "evolutionary" for my "style" of sex that does not involved penis jamming in and out of vaginas? How is it a survival tactic for me to get off simply by kissing until She convulses in a blast of orgasmic ecstacy? What's odd is that She really doesn't need to have an orgasm to procreate. Yet, for us, Her orgasm isn't physically involved in reproduction nor is it my goal. Since I don't give my DNA to Her, my orgasm isn't involved in reproduction, either. What kind of reproduction strategy is this???
