If your gf can get a copy of her blood test results to post here - I can take a look at them to make sure she doesn't need any additional confirmatory testing. I just need the numeric values - ie hsv1 igg 5.6 and hsv2 igg 4.7 or whatever they are.
I encourage you both to read the herpes info here on asha as well as check out the herpes handbook at www.westoverheights.com
. both have lots of good info in them about herpes and how to reduce your risk of contracting the virus from her. I'm glad you chose to educate yourself on this very common virus instead of just thinking it was something you shouldn't have to deal with!
As for oral sex- hsv2 prefers the oral area but it can infect the genital area. Of course avoid performing oral sex on her whenever she has any genital symptoms. If you think you'd be more comfortable with barrier protection then utilize it - either a dental/oral dam, a condom cut open and laid over her genital area ( unlubricated and flavored ones sometimes improve the taste ) or even saran wrap. You can also consider her taking daily suppressive therapy with valtrex to help reduce your risk for all sex acts. Your risk of contracting hsv2 orally ( and genitally ) is actually rather low but it's totally your choice what precautions you want to utilize.
