Jasmine,
Sorry, I didn't see your first post. Sadly, I admit I have the same issue. The drugs or cream never worked for me and IMO weren't worth the money. I also find that my outbreaks are friction related, not stress related. Point in case - after my long ride this weekend I have a blister.

To prevent I agree with Brandi - keep the area well lubed and remove those shorts as soon as you're done and get the area dry. If you get an outbreak, keep the area dry. Believe it or not, my dr. recommended drying the area with a hair dryer after a shower/bath. It helps the healing process. Anti-itch creams help with the annoying itch. If the sores are internal, all the more reason to try and keep it dry. Feel free to go commando around the house if necessary.

As a tri athlete I think friction could be a big problem for you, but stress does play a part for some people. You need to identify your trigger and eliminate it. Some people will get a tingling feeling before an outbreak to warn you. Take note if you do. Obviously, no physical activities when you have an outbreak but I'm sure you know that.

Hope that helps some.
