Planned Parenthood. It's safe, fast, and they're super nice.

I get tested in a lot of different places, as I'm a mystery shopper for sexual health clinics, but when I need to get tested and I think I've been at a decent risk of exposure I go to 56 Dean Street clinic in Soho, London. It's a clinic aimed specifically at the LGBT community and I recently helped train stuff in trans* related stuff so I feel much safer there.

I get tested usually once a yr at a mobile testing center during pride

I always opt to get tested during my annual gynecological check ups at the local Planned Parenthood, so once a year for me.

I get a full blood panel done, including STD's and STI's, a couple times of year. My doctor is big on blood work. If she weren't I'd still be getting tested once a year by request, or by going to Planned Parenthood.

I've never been tested, but then again it's not an issue for me. I know there's free testing at my university sometimes.
