If this theory is correct, the reason we have sex is to out-evolve germs.
Some theories are obviously flawed from their point of conception.
All of that mixing up of the gene pool stuff is fine, but that's not why I strive to have sex John.
I would rather, at this point in life, not pass my DNA on to another generation of little mutant wannbes, and yet in a perfect world I'd have sex every day. Several times in fact.
Asexual reproduction may indeed be the most efficient way to pass DNA on to another generation, (for the last few months of my marriage I was actually worried that might happen,) but the problem with asexual reproduction is obvious. There's no sex involoved.
The only reason people have sex is because you get to have sex while doing it. People would have sex while eating dinner if it wasn't so messy.
People would have sex while driving across I-80 in Nebraska just west of Kearney if their partner was petite enough to be able to get on top and clear the steering wheel , and the seat could recline a little, and they could use cruise-control, and if it was late enough at night so that there was like,,,no traffic.
I'm sure more than one person has sat in an IRS office thinking.."Ya know, rather than being audited right now, I'd rather be having sexual relations with someone." They don't think "Gee, too bad I have these sexual organs and urges. If I was an asexual species, I could be audited by the IRS, AND pass on my DNA at the same time. That would be so much more efficient."
Nope. In my mind, having sex is all about having sex, and for the last 3 weeks, in my mind is where all of the having of the sex has occurred. As I become more and more insane from the lack of sex, do I wonder: "Is this nature's way of insisting that I pass on my DNA?"
No, because I'm sure that isn't what Mother Nature is saying. If fact, I'm sure Mother Nature has more important things to do, what with global warming, deforestation, pollution etc. Not to mention the fact that it's Mother's Day.
No sir, the "I need to have sexual relations, and soon" signal I'm getting is coming from much closer to home. The transmitter is in my jeans, not my genes. It's my body's way of saying "God damn it man, you're not an asexual species you know. Go have some sex. It feels good, and it's good for you. And if you're any kind of sexual creature, you'll make sure it's good for your sexual friend/companion too."
If one happens to procreate, well that's just a bonus isn't it? Imagine the doctor telling you that, not only did you have the aforementioned sexual relations, not only was it fun for both of you, but you're also going to be the proud parents of a little mutant wannabe who will grow up and some day start having sexual relations too. Imagine the doctor telling you that your DNA was going to be passed on THREE TIMES in one sitting. I can only imagine that having triplets makes the sexual relations part three times more satisfying, even after-the-fact.
