1 John 2:15-17
Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. For everything in the world--the cravings of sinful man, the lust of his eyes and the boasting of what he has and does--comes not from the Father but from the world. The world and its desires pass away, but the man who does the will of God lives forever</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif"> </font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif">1 Peter 2:11-12
Beloved, I implore you as aliens and strangers and exiles [in this world] to abstain from the sensual urges (the evil desires, the passions of the flesh, your lower nature) that wage war against the soul. Conduct yourselves properly (honorably, righteously) among the Gentiles, so that, although they may slander you as evildoers, [yet] they may by witnessing your good deeds [come to] glorify God in the day of inspection [when God shall look upon you wanderers as a pastor or shepherd looks over his flock].</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">obviously the amplified version

Let us behave decently, as in the daytime, not in orgies and drunkenness, not in sexual immorality and debauchery, not in dissension and jealousy.

Galations Chapter 5 Some highlights:
"It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery."
- If you believe that you "really have to do it" then you are in bondage/slavery to it, whether it is sinful in someone else's eyes or not. It would be the same as with someone who eats themselves overweight, drinks themselves drunk, smokes cigarettes after every meal, when waking up, etc. (oops, stepping on some toes

), etc. It is something you are allowing to control you, you aren't controlling it. There is a freedom from that that can be found.
"A little yeast works through the whole batch of dough."
- allowing something in that maybe technically ok, may open the door for other things that seem a little more ok.
"You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature; rather, serve one another in love."- again, a call for freedom.
"So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want."- that you may have life and live it more abundantly.
"But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law." I can't say it any better.
Is it sinful? Who knows, we'll never find that out, depends on your intent and thought processes. If it is something that you allow to control your waking thoughts, then there is freedom available from that.
