Keep this in mind: You are living as a prisoner of other people's thoughts. Back in the Isarelite/Hebrew days, when a young man fancied a woman, he took her home, shagged her, and the next day the families had a celebration. You made darn sure you loved the girl for all time, had sex, and you were married. There was none of all that other chaperone crap, paper work, marriage licenses, etc. So mankind has created all these secular rules about what is marriage and made it into a big legalistic hubbub. At any rate, if you live the life the WTBS wants you to live, you will be single for a LONG, LONG time - they want you to have the special gift of singleness and God will kill you if you masturbate. The sisters grow old and become old maids and end up being cat ladies with weirdly shaved eyebrows. The longer people are single, the more maladjusted they usually become.
The time to have a girl and get married is now because the longer you wait, the more baggage they will have - kids, someone else's screw-toy, riddled with everyone else's diseases, failed relationships, etc. Oh yeah, they will have a field day with you about not being baptized and talking about being unevenly yoked. Ask any of them to show you where in the Bible getting married without being baptized is a disfellowshipable offense? The worst they can do is ban you from having your wedding in the Hall. Big deal. Go have it at a park, mountain, or some really cool place. The Witnesses around here gave my wife and I the serious cold shoulder when we were dating and we were middle-aged!!! They completely ruined the happiness we could have had if we had found someone and gotten married sooner. Our wedding almost felt like a funeral in restrospect. Anyway, If you can't be trusted when your *ick is half limp and the raging hormones have left your body (when you're older), then there is something wrong with you. On a personal note, I would seriously suggest waiting to have sex after marriage - not because of purity issues and all that - just because it's worth waiting for someone you really love. It makes the relationship really strong. You can just shag around if you want, but a lot of people will tell you that in the end, it leaves you feeling rather empty - as if it just isn't as special anymore. Also, while you're busy screwing around, people are getting married, and one day you wake up and ALL THAT IS LEFT is sloppy seconds and thirds - with kids - with issues - and you're left wondering why you cashed in all your chips so early. At that point all you're left with is a limp shaft that doesn't work any more and you're still alone. Anyway, as a last resort, you can fight fire with fire and deny it. It takes 2 people to witness something and be considered true. Under the law, you've done nothing wrong. I concur though - do NOT get baptized just to be with her and at age 21, you're no longer a minor, so you do have to make a choice - do you want to live under their rules for the rest of your life or do you want to get on with it, start a life, and be happy? Jehovah wants you to be happy and get married to someone that your heart desires. One thing you will find out, when you want to even consider being with a member of the opposite sex in this religion, suddenly your life BECOMES EVERYONE'S BUSINESS and they will stop at no end to hang you, kick you out, and find fault with every single thing you do. They turn into ravenous spies, back biters, etc. because they just can't stand the thought that someone might commit a horrendous evil known as sex! The both of you better not be living with your parents because it's EVEN WORSE!
