You should be speaking to an adult you trust about questions like that. There are informative books you can get from libraries (or possibly a school) that can better explain it and what all happens.
Though if you really are 10, (as you stated in another post) you might want to consider waiting a longer time to even be bothered for ANYTHING like that. You're still a child. Be one, and don't worry about sex or pregnancy or how you do it. There's plenty of time in your future before any of this should matter.
