Men who are not experiencing symptoms and don’t need PEP or PrEP advice
Men who are not experiencing symptoms and don’t need PEP or PrEP advice can get an online sexual health check-up with Sexual Health London. If you live in a borough where the Sexual Health London service is not available, you can find your local service either through SH24 or NHS.uk (NHS Choices).
