Frequently Asked Questions


When should I go for STD screening?

You should consider screening if you have symptoms of a possible STD, if you have had a recent risky exposure (unprotected sex with a casual partner), or both.

Can I get STDs from oral sex?

Yes, you can. The common misconception is that oral sex is not considered ‘real’ sex and therfore has no risk but the opposite is true. Often oral sex is performed without protection and this is why infections such as chlamydia and gonorrhoea can pass on through oral sex.

Can STDs be cured?

Thankfully the majority can be cured but there are some such as Herpes and HIV that can be treated but not cured. This is why prevention is better than cure and ensuring safe sex goes a long way to reduce your risks.
