LaurenM,
Yes, "listen" to what V1922 just said. It's true.
A guy is a guy, JW or non JW or whatever.
And, not to be crude, but we guys are all the same "down below",
And, the problem is that the "down below" has a mind of it's own.
It's only when a guy evolves morally, ethically, spiritually, or whatever you want to call it, that they begin to gain "control" over their sexual impulses.
I'm not a JW and know very little about it, but from what I've learned recently, this is one area where the JW rules, beliefs, can actually be a big help/protection to you. At least until you gain some experience in dealing with guys.
I've had more than my share of "fun", and of course it's easy to say this now, but honestly if I were a girl, knowing what I know now, I would not "sleep" with any guy unless he is "husband material".
If you have "casual sex" you are, among other things, running the risk of catching a sexually transmitted disease. Some of these lurk in your body forever and never go away.
I'm sure you wouldn't want to put your future husband at risk and/or your baby coming through the birth canal.
Good Luck
