Yes: But why? If you've never had lesions u may go a lifetime w/o developing these. Most adults have been infected by and are carriers of herpes simplex. Once in your body it is permanent. There is no need for Acyclovir unless to limit the frequency of outbreaks or to treat an acute outbreak. Your husband has already been exposed to you or had it prior. Check his antibody.
