Your positive monospot means you have classical infectious mononucleosis, which is due to Epstein Barr virus (EBV); unless there is a surprising coincidence, you can expect your CMV and HIV tests to be negative. CMV can cause monospot-negative mono, but most infections are asymptomatic; and almost everybody is infected with CMV some time or another--so a positive CMV test won't mean anything. The liver function tests are because mono due to either EBV or CMV often causes mild hepatitis, and once in a while a severe case, but that is uncommon.
There is no particular reason to suspect HIV. The symptoms of acute retroviral syndrome (acute HIV infection), when such symptoms occur, are identical to those of mono/EBV, but mono is very much more common. It is transmitted primarily though saliva, and onset 2-6 weeks after french-kissing a new partner is very typical. But you can rely 100% on your negative HIV test (which is certainly what the result will be) when the result returns. Search the STD forum threads for "time to positive HIV test" for much more detail about this.

I posted not long ago (post titled "Severe HIV Scare") and my symptoms resembled yours almost identically. Even my situation, very, very similar. I've been in a faithful relationship for years, and just recently experienced a single incident of unprotected sex, though lengthier than yours, no ejaculation. I had (still have) swollen lymph nodes in my neck, which seem to be pretty stable, as they've been there since approximately the 4 week mark (it's now been about 4 months.) Anyhow, if you're interested in a more thorough description, you can read my post. Severeral helpful people replied, including Dr. HHH.
Thanks KC20 and Doc - very helpful!
