You need to get tested after about 3 weeks, then repeat the tests after 3 months (syphilis / HIV can take longer to show up in the tests). There's no need to panic though, as someone else said, WG's take their sexual health seriously, but as punters so should we. Sexual health is the responsibility of your local council now (GUM clinics are still run by the NHS but funded by the council). In response to this a lot of councils now offer free home testing kits (it's cheaper for them), ordered online, it arrives in discreet packaging, you post your samples back and receive a text with the results in less than a week, there's no excuse really. Sorry, lecture over!
