You're worried about HPV? Honey... If you're a SW, you probably have HPV. 80% of sexually active people have HPV.

Not to say you shouldn't still set whatever boundaries you like (cbj, etc)... That is all fine. Feel free to protect yourself in any way you see fit. But just letting you know that if you're having sex, you probably are going to get HPV and the only way you'll know is if you get warts, which makes up about 1% of sexually active adults.

Don't believe me? Google it. CDC website lists all the statistics.
