Symptom #3 Believing that your stable partner will never infect you.

HIV does not have symptoms. But there are people who think that they have to use a condom with everyone except their partner.  Why? “Because my partner loves me”; “Because he would never have sex with another person”; “...and if my partner did, it'd be with a condom.”  But the reality is different: We don't know what our partners do or don't do when they're not with us and the majority of people get infected by their committed partner, mainly in “closed” relationships, since those in “open” relationship usually more conscious of the risks or at least there is certain freedom to talk about it.
