Yes, it is possible for a man to contract HSV2 from a woman even if she does not have any visible outbreak. This is because herpes can be transmitted through skin-to-skin contact and shedding of the virus can occur even when there are no symptoms present. It's important to practice safe sex measures such as using condoms consistently to reduce the risk of transmission, especially if one partner has herpes. If you have concerns or suspect exposure, consulting with a healthcare provider for testing and guidance is advisable.
