Performing oral sex on a woman at any time, especially while she is menstruating can put you at risk for STD’s and some viruses, so it is best to use a dental dam during this foreplay activity.
If you are not going to use protection, you are essentially always at risk whenever you are sexually active because you don’t know how faithful your partner actually is.
