I agree with all the other posters . If someone was raped during the time of being in a relationship , in that situation the partner should be informed because of risks of any sexual transmitted infections . But other than that I think it is completely your choice . I also think giving the name of every partner that you have ever been with seems a bit unessasary . When people start a relationship they are free to both go for sexual health check ups before they start having sex together . I'm not saying lie to partners but I don't think so much detail is really necessary .
