Wow, you seriously need to do some reading on HPV and HSV. Despite sharing similar initials, they are completely different viruses: Human Papilloma Virus (warts) and Herpes Simplex Virus.
Virtually everyone gets HPV at some point, and regardless of who gave what to whom, surely you are both infected by now. You don't ping-pong either virus. I'd say no further protection against HPV is needed.
The herpes thing is another story. She should ask her doctor for a HerpeSelect blood test to see if she has HSV2. If so, you don't need to take further precautions. If not, then you might consider going on suppressive therapy to reduce the risk of transmission. Also make sure you wear condoms, which are pretty good protection against HSV. But even if she does get it, for most people it's a total non-event. Certainly not something worth breaking up over, for god's sake. And for what it's worth, since about 25% of people have genital herpes, avoiding them is going to seriously reduce the pool of available partners...
First, read Dr. Handsfield's STD board for his advice and info about HPV and HSV. Then check out www.westoverheights.com; they have a herpes handbook that would be very helpful to you both.
And relax. This is not a big deal.
Oh- and re: blood donation--of the STDs, they only check for HIV and hepatitis, because they're the only two bloodborne pathogens.
Even though she's allergic to latex - you can use polyurethane condoms if you are interested in using them as another precaution against her contracting your hsv2.
If you've never read the herpes handbook yet I highly recommend it - www.westoverheights.com/freebook.html
I totally 2nd monkeyflower's post - your hsv2 and her hpv/dysplasia have nothing to do with each other. She already had issues before she met you from the hpv from the sounds of things. I hope she gets a quick resolution of her problems quickly so you two can get back to normal soon and have less to worry about :)
Has she looked into any of the terrific research going on right now with hpv and dysplasia on clinicaltrials.gov?
