it doesnt matter if it doesnt affect him. if you two were to ever break up and him get with another girl he can pass it on to her. just because it doesnt show physical signs doesnt mean he cant be a carrier for it. plus, you need to have him tested to make sure thats who you got it from. if it is then he needs to do some calling around to his past girlfriends.

why wouldnt you want to tell him in the first place? you need to be open, not just for your and his sake but for future boyfriends/girlfriends whatever.

there has to be open an honest communication between the both of you. kind of bothers me that you have been together for so long and havent told him any of this. hiding the information wont help you get over it.

you might be suprised at his reaction. lately i have had to come clean about some things from my past that i thought would make people view me different and instead i got the total opposite reaction. i got caring and support. people will always suprise you so i would go out on that limb and tell him strictly for the sake of clearing your own conscious. if not for that, then for everyone's health because you never know how many people this could end up effecting.
