Some type of yeast infection or something else? *pic*

I have an appt with my gyno on Monday, but I'm a little freaked out by all of this and want someone's opinion.  This picture is after 5 days of burning and severe itching.  The itching and burning has subsided since then, but for a few days I had trouble walking and even getting in my vehicle.

Last week I was dealing with a hemorroid and severe itching. I probably should not have scratched, but I did. Five days ago, after a trip to the gym there was severe itching on my butt crack (for lack of a better word), and I see this type of infection occurr. I've never experienced this before, and have only slept with one person for the last 8 years. I am hoping it's some type of yeast infection because of prolonged use of sweaty clothes, but I am deadly scared that it is herpes that has lay dormant for years. It's odorless, and the discharge is more of a greenish color. It is right in the butt crack, and it doesn't hurt when using the restroom. Please help. Thanks.
