How does sperm from one earthworm enter another earthworm for cross-fertilization?
Two worms come together along their ventral sides and become temporarily joined by the secretion of a "slime tube". Sperm is discharged from the seminal vesicles of both Worms's long seminal grooves on the ventral body surfaces, and enter the seminal receptacles of the other worms.

Do earthworms mate for life?

What are the tubes in which the sperm have to travel through on the way out of the body?
The sperm are formed in tubes called seminiferous tubules. They then travel into the epididymus (another tubule network), up through the ductus/vas deferens (another tube) up the front of the pelvis then over the top of the bladder nad back down posterior to it. Here they enter the ejaculatory duct (another tube) which empties into the urethra (another tube). Take you pick.
