Re: sex+sperm question.
No offense dude but you're only 14 and you shouldn't be worrying about sex. You obviously are not educated with sex or puberty and that's a must when considering sex so you can understand the consequences of it like STDs and pregnancy. Not to mention method of birth control, condoms, etc. Then what to do if she gets pregnant. Adoption? Keeping the baby? Have I made my point? You're too young to be worrying about sex. Don't make the mistake and wait.
Just because you don't have a wet dream doesn't mean you aren't producing semen. If you masturbate then if semen is produced during orgasm then you obviously are. If you have dry orgasms then you aren't fully developed to produce semen yet.
