Are you serious...? How old are you anyway..? If you don't know that answer you shouldn't be having sex...! DO NOT have UNPROTECTED sex at all..! Not only is HIV (the virus that causes AIDS) contagious but many other sexually transmitted diseases. Certainly you know that this also could cause unwanted pregnancy right..? Apparently not because you actually believe that by pulling out before ejaculation that pregnancy is ruled out too. Do yourself a favor and hopefully anyone else reading this that doesn't know consequences of unprotected sex and go to a web page that expains pretty much all you need to know about 'safer sex'. I'll list one below for you.

What really scares me is that you are old enough to go to bars and drink but do not have a clue about sex. Judging so far on this website many of you should be reading sex ed books instead of having it, but at least some of you are asking questions BEFORE they do the deed. I don't mean to be harsh on you but for real now, you are seriously potentially getting yourself into lots of trouble just because you didn't research facts.
