Hey and welcome to the boards.
From what I've asked doctors, female condoms provide more surface coverage so they could be helpful in reducing trasmission. Keep im mind I said reducing transmission. HSV -2 is skin to skin contact so whereever the condom is not covering, that is an opprotunity to contract HPV. Female condoms can be purchased usually at most drug stores like CVS or Walgreens. There are some store online that sell them. Just google the name female condom or even try drugstore.com. They can ship you some if you can't find them. Also try a store that specializes in condoms as weel.
Also I have not heard of any long term side effects from using suppressive therapy and your partner should really consider taking an antiviral medication. Antiviral medication can help reduce tramission of the virus to partners, reduce viral shedding on the skin, reduce the duration of an outbreak and the symptoms of an outbreak. Here are two sites you should check out.www.famvir.comwww.valtrex.com
Alos for cost effectiveness, he can take the standard that started them all, acyclovir. Valtrex is an updated formulation. Usually those who take suppressive therapy reduce the amount of outbreaks they have as well as reduce transmission rates of the virus. I take famvir in episodic therapy when needed. I currently have HSV-1 only and for me Famvir has been a lifesaver and it hasn't slowed me down in the relationship department as well
Before you have any relations, your partner should consider a therapy if he is having outbreaks. It helps to protect you and reduce your chances of contracting the virus. Just my two cents.
