Is it possible? Perhaps, at least in theory. However, no such case of HSV transmission has ever been reported and I certainly have never seen any patients in whom there was suspicion they caught genital herpes that way. Even with unprotected vaginal sex, the chance of transmission is pretty low for any particular episode of sex, and is even lower when the infected person is taking an antiherpes drug like acyclovir.
Bottom line: No significant risk, nothing to worry about.
