1. If you make out with someone and there is no cold sore on their mouth at the time you makeout with them—-then 1-2 days later they develop a cold sore, can that pose as a transmission risk?
Yes
2. So if both persons have oral HSV-1 & they perform oral sex on each other, can they transmit the hsv1 to genital still?
That would be extremely unlikely
3. How long does HSV-1 live on plastic toys, straws, glass cups, etc?
We don’t have an exact answer for that but a short time
4. If you make out with someone and wipe hand sanitizer on your lips, can it kill HSV infection?
Probably, but yuck!
5. Do you recommend new love interests to do a western blot since IGg misses 30% of cases? Incase they have HSV-1 & they want to perform oral sex on you? Thoughts?
Depends on how worried you are about getting herpes, I guess.
