Absolutely no shame in going to the clinic to get tested. I'm sure I speak for everyone who's ever done it, the first time it's pretty scary. You're afraid of being judged by the people who work there & maybe even your friends/BF/gf. However, there's no shame in making sure you're clean/safe. More harm can come from not going. It's probably something everyone should do every so often. The workers were trained for this particular thing & they're there to help you! :)
