How can herpes be passed on from a woman to another woman? is there a way to get genital herpes through oral sex if i have it and she does not?

Depends on immunity: If immune to Herpes type 1 she should not be able to catch type 1 again, but may have outbreaks at locations where she had it originally. If immune to type 2 she should not be able to catch type 2 again, but may have outbreaks at locations where she had it originally. If NOT immune to type 1, she can catch type 1; if NOT immune to type 2, she can catch type 2; at locations where she is exposed.
