What are the chances of you not getting an std by someone who has one?
Low enough to not take the risk.
Yes, you can, but the chances are low. You can get and STD from someone who has one if you are in contact with any of their bodily fluids; blood, saliva, sweat, semen, urine. Chances are you won't get an STD just from biting but it is possible. If you are wondering whether or not you have an STD, get yourself tested. The sooner it's diagnosed the easier it is to treat it. -5L4D3
BV is not a STD. Having sex can cause BV because it may cause an increase in harmful bacteria in the vagina. Multiple sex partners increases the chances of getting BV. Bacterial vaginosis is not an STD. It's not clear. BV has been previously classified as an STD but the CDC seems to be reconsidering that position.
