Is it possible to have sex with some one with hepatitis and not catch it?

Yes, but why chance?: Repeated exposure increases your risk (its like rolling the dice again & again). Different kinds of hepatitis virus are more or less effectively transmitted sexually. Having the male partner wear a condom is some protection, but really...Why take the chance until your partner is treated & the virus eradicated? If you have been exposed, get blood test to see if you got it, can transmit it to others.
