So my friend and I were, you know, checkin’ out some tide pools the other day, and of course STIs came up (this is actually totally normal in the life of a sex ed teacher and TeenSource blogger). Anyways, she’s a super smart girl, been through sex ed a few times, and knew what was up when it came to birth control… so it was kinda surprising to hear her ask me “So… what are the STIs that I could get, you know, if I start hooking up with someone new?”
