Yes. There is an attraction (to the opposite sex). It's natural. It's overwhelming. Nu? So what? Are you saying that in the long run it's hopeless? Good! If so, you may qualify as an addict, like me. Cuz it's hopeless for me, too. Completely hopeless. Left with my own resources alone, I will eventually act out using lust. And it will eventually ruin my life and kill me. Nu. Mazel Tov. No chiddush there either, for me. I am an addict. I have a chronic progressive and fatal disease, like any other. But there is treatment that offers a daily reprieve, by finally/really getting a G-d.
For an addict, the 12-step folks I hang out would honestly suggest, "Go right ahead and enjoy yourself. If you are looking for a minute of enjoyment who can stop you? And if we did stop you, then what would it avail you in the end - or tomorrow? When you decide that you have had enough stupidity and that you want more out of life, come back and we'll share our solution with you so that you can start really living rather than running."
I wouldn't say that, though, cuz I'm a really nice guy :-)
