How "the bug" propagates?

[Ready2DoThis]

I have a friend who says that once a guy starts doing bareback there is almost no going back. He also says that once a guy starts allowing guys to cum in him (and then absorbs that cum as opposed to pushing it out) that it changes him to want cum more and more with each load. I can arrest to both of those being true, at least, for me. He also believes that there is a chemical component in poz cum that, when absorbed, rewrites the bottom's DNA and creates the desire for more poz cum. This happens even if the bottom doesn't convert to HIV positive because the virus is simply opening him up to continued exposure until the inevitable finally happens.  The theory is that the virus subtly rewrites the bottom's DNA to strongly desire it and this is how the virus ensures that the bottom will continue to take those loads until he too is converted. Once converted, the virus creates the desire to breed others to continue to pass the virus on. (Google "zombie ant fungus" to see how this occurs in nature.)  In a way, this all makes perfect sense because the HIV virus, like every living thing, wants to live and propagate. I guess the lesson here is, if you want to remain HIV negative, don't start down this road but I'm guessing that it's probably too late for many of us here. Do you think there is any merit to this theory?

I think it's all about the thrill. Once you take the load, regardless if it's poz or not, you are hooked. Being uncertain releases a lot of emotions, but at the same time you've tried it, you are ok with and you want more.. way more, after all that's what's you've been thinking about for a while, isn't it? 

I don't believe in the DNA rewriting and zombie like effect.

I'm not certain yet which way to go on the issue. There seems to be evidence supporting that it is possible for the poz load to rewrite the bottom's DNA to make him continue to take loads.

I’d be curious to see the evidence.
