What can I do about it?

Get yourself checked out. If you have itches, sores or blisters around your genitals, you probably have an STI. No need to panic, but you should contact your local sexual health (GUM) clinic immediately.

Sexual health check-ups are free and available to everyone in the UK. You can arrange a visit to a sexual health (GUM) clinic anytime. It is completely confidential.

Condoms are essential wear: Always use a condom every time you have sex, as this is the best way of making sure you don't get a STI - It's not just a bloke thing either, women buy 4 out of every 10 condoms sold.

Condoms come in a wide range of sizes, flavours, colours and shapes and are available for both men and women. There are allergy-free versions and even vegan varieties, which use no animal products including milk- so there's no excuse for not using one.
