What do I do if my girlfriend gives me a sexual disease?

The first thing to do is get tested. Go to a sexual health clinic or your GP and get checked. It's free and confidential. If you do have an STI, they'll tell you what it is and how to treat it. Most STIs are curable with antibiotics or manageable with medication.

Both of you need to get tested and treated. If only one of you gets treated and the other doesn't, you'll just pass it back and forth. This is one of the main reasons STIs stick around in couples.

It's also worth knowing that STIs don't always come from your current partner. Some STIs can sit in your body for weeks, months, or even years without symptoms. Either of you could have picked it up before you got together and not known about it. Jumping to blame doesn't help, and it's not always accurate.

Have a conversation with your girlfriend about it. It might be awkward, but it's necessary. If she gave it to you without knowing she had it, that's different from knowing and not telling you. Most people who pass on STIs genuinely didn't know they had one.

Don't have sex until you've both been tested and treated. After that, use condoms to reduce the risk going forward.
