it's not that you'll "re-give" it. you already have it! it's a virus, and it never goes away. But, it is possible to infect other parts of your body. Right now the virus is centralized in one location on your body, but with careless activities, it can spread, which could be what she means by worse.. Besides that, your body builds antibodies for the virus, so the longer you have it, the more your body is able to supress it, so to say that it gets worse in that regard is bogus. So, at this point, it's really more of a personal decision you and your boyfriend would have to make. Do you want to use condoms or not? are you willing to take the chance that the virus will spread... perhaps down your thighs? you're dealing with a situation where the negitive effects are slim, but possible. and it's up to you how careful you want to be.
