If you have sex with the person who passed on HPV to you, you can't re-infect each other and you can't make it worse. Once you have the virus you have it.As far as it being safer to stay with the person who gave it to you that is a personal choice. If the relationship is unhealthy then move on but if the relationship is loving, supportive and nurturing then continue.
HPV is a very common virus.Here are two websites:www.hpvtest.comwww.maketheconnection.org
