I've just start reading these forums, and as I read them, and this one in particular, I find myself combating the vice known as lust even at this very moment.
I'm a student of conversation and human-kind. I've spents years now studying what we are and why we act, what our soul is and what the man in us is responsible for, while at the same time learning to seperate that from the tools of the evil which also finds opportunity in our individual souls.
With that knownledge and realization that I am only a student, and not yet a teacher, I have to decide when it is appropriate to speak out to others and with great care give them information that will not harm them, but help them; for I(like anyone else) will be held responsible for what I preach.
On that note I'll kept my advice very simple and hopefully accurate.(Right now you are IN the situations on a daily basis, so I'll cut it down to the practical parts)
Define what it is that is troubling you. In this particular circumstance it is Lust.
Lust is a vice of mankind and in that, you need to assert unto yourself a definition for understand it in this instance and future ones to come. From there you can always see it coming, and deal with it, commanding it and taking dominion over it.
So, having said that I'll give you my own, and hopefully give good witness.
Lust is your willingness to disobey, in order to obtain something you want.
If you disagree with this statement, that is fine, but it has seen many trials, so combat it with not only what you've been told about your current situation but the circumstances of others as well.
If you feel lead to work with this definition until you can better hone it yourself over time, then compare it to your situation and make sure that it is lust that has you troubled.
Otherwise concern yourself with the human body, and your own hormones. Consider that it is those very levels of testerone that can cause men to commit murder and defile woman by rape. Assess your young self and realize that you have a lot of time to grow, and decide for yourself if you need to become more deciplined. That is a very hard thing to do, and it take a strong heart and mind,but sometimes we are that passionate, and sometimes our hormones do hold that much sway. In those circumstances we have to hold ourselves accountable and strong that much stronger.
It is through ignorance that God's people are destroyed.
