WHY? Over and over and over. Unless maybe many/"most" who water here think they have FULL CONTROL over what they like/desire in a mate? Or just WHAT turns them on? Or OFF for that matter. You don't really think Mother Nature is going to allow that do you? Mother Nature is why our brains go though so many gyrations everyday to try and protect us from ourselves in all manner of things.
Feeling guilt and shame for something Mother Nature has bestowed you with is rather silly is it not?
