let me re-word that. ha. it sounds weird and I can't figure out how to delete it.
Basically I don't want him to know I have been having sex while we have been broken up.
thanks everyone for your advice!! I know I should tell him I have an STD, I just don't want to tell him it's most likely from a guy since we have broken up!!! I know telling the truth is the best thing though.
I think that you should just tell him, and like ania_2 said, dont you wish that person who gave it to you had told you they had an STD? You should also talk to your doctor, or a doctor about ways to prevent spreading the STD to other people and/or treating it now. If you decide to have sexual contact with any other people, including oral, you should use some sort of protection. You have to make all of your partners aware of your STD, including past ones that you could have given it to. If he really likes you, then he'll understand and won't be mad or stop talking to you. Also, if you tell him before you two decide to start anything sexual, he'll probably respect that more than if you didn't tell him until after. Good Luck though!
Be honest with him if you really care for him. Don't let things get to the point where you don't tell him and your relationship progresses to become sexual. He has a right to know that you have an STD. Don't you wish that who ever gave you the STD had told you that he had one?
