My two cents,
First of all: what's obvious to me, for me, is that being with young, beautiful, laughing and smiling chicas makes me feel young again. I can't believe that no one mentioned feeling young with young women.
Second of all: there's a biological explanation as to why men like to have sex with many different women. I read it somewhere and well, having considered it, it makes sense to me.
Consider that, when a woman has a baby she KNOWS she's the mother. But the father can't be sure he's the father. Yeah. Sure. Now we can with DNA testing but throughout our history we couldn't.
Now I'll be the first to admit that I don't like the idea that my behaviour is coded into me. I have to admit that I believe it is though. I mean, life would be so much easier (less frustrating) if I could just not be attracted to women. What's the big deal? Their body parts are just slightly different than ours right? When you break it down and analyze it WHAT'S THE BIG FREAKIN DEAL? Trouble is, our attraction to them isn't rational. It IS biological. I believe it IS coded into us to seek young, healthy mates - even though nowadays we do our best to keep them from getting pregnant. If this urge wasn't coded into us we just wouldn't be here, as a race, to discuss the point.
So ladies! It's not our fault we're dogs! We can't help ourselves.
