your question is too broad. Herpes isn't a virus that can be "treated" per se. You will always have the virus, but there is medication to treat you when you break out. Herpes does not have any long term consequences on your health. The only thing you have to be aware of is that herpes can and will increase your chances of acquiring HIV, but that's only if you have unprotected sex with someone who is HIV positive, which you shouldn't be doing anyway. As for bacterial STDs, they're all treatable.
so untreat herpes can become HIV or it easily when we have to have sex with a HIV+ to get it
NO! Herpes and HIV are two completely different viruses. If you have herpes and you have sex with an HIV+ person, it will be easier for you to get infected with HIV than if you didn't have herpes and had sex with an HIV+ person.
I suggest you don't have sex UNTIL you do some research on the internet and find out about STDs.
