The love virus

No not the high 5. Something useful. I watched a show on National G that revolved around the concept that viruses drive evolution and all sorts of things. It makes sense, I buy into it. It also explains all of the "junk code" in DNA... Well, that is crap I think, scientists are calling it junk because they don't know what the hell it does or what the hell it once did. So, anyway, they had these two strains of prairie vol. One type was known to be monogamous, the other type was known to spread his seed far and wide. They took one of these "playa" vols and injected him with this virus found in the monogamous species. The little pimp turned into a home loving man ( or little furry thing, whatever). Simply amazing! Everyone releases chemicals into their own blood stream during sexy time. There were 3 specific ones named. One is responsible for pair bonding, AKA love. Oxytocin??? Which is the same stuff that causes labor. At any rate, the playa vol released it but without that virus the chemicals were not reacting in the brain and changing behavior, the virus acts as a catalyst.
There have been a small handful of women that I have been absolutely addicted to. I would never in a million years have thought of cheating on them, and when we parted, for whatever reason, I was seriously messed up. But with all other women, it's been fine, even some that dump me. I have been like... enh... ok, next.
Put the TV show together with what I just wrote about and it brings all sorts of questions up.
1. Was I infected?
2. Who carried it?
3. Am I now immune?
4. Will I need a booster shot?
5. Do I want a booster shot?
6. Can I keep myself single by using disinfecting wipes consistently?
7. Am I a carrier?
8. Can I spread it to others?

Ah, the love bug... literally, that may be what it is. At any rate, I hope to god that if I come down with love again it does not end in a train wreck.
