What degree would I need to be a sexual health nurse for young people?

I would like to be a sexual health nurse/paramedic when I am older. I have looked at both and I understand how I would get into paramedics but for being a sexual health nurse for young people at a drop in centre/clinic would I have to do adult nursing or children’s nursing? Obviously general nursing is no longer a route you can take as the degrees are now specified ones. If anyone can offer me any advice I would really appreciate it
