I think it is unlikely for several reasons.  First, HSV 2 does not like the mouth (we don't know why not) so it rarely infects that area and if it does infect there, it rarely recurs or shed from there.  Second, the valacyclovir is going to go a long ways to reducing viral shedding and thus infection.  I'm sorry that we do not have any specific research on this question of genital to mouth infection with HSV 2 but given what we do know from other studies, it is quite unlikely.  Impossible?  No.  Unlikely?  Yes

Can transmission happen from genital skin contact (beyond area covered with condom) and menstrual blood? To make the question simple: can menatrual blood be infected with hsv2 and contaminate the skin (ex: of men’s genital) 

Thank you in advance for your reply

Yes, it is possible that any fluid coming out of the vagina could have picked up virus from tissue that has been shedding virus.

Yes, antivirals reduce that risk substanatially
