Yes semen is, normally, constantly produced. I say "normally" because a very few people have a sexual disorder where they can't produce semen. Don't worry about that though. To answer your question, semen is produced always, while eggs(female sex cell) are never reproduced.
No, but there can be slight premature ejaculation, this is often just a small amount of semen, but it is enough to fertilise an egg.
