If I turned down his sexual advances, would he act on them with YF2?

I don't know. Probably. If, as you say, he is doing this for sex only and not for a deeper relationship, I'd have a problem with how he is advancing on you. Recreational sex is the addictive element I'm talking about.

You stated to youth??: The sexual feelings I have towards him developed after I started being physically close to him.

The farther you go, the more you experiment, the more your body wants and craves the action. When sex becomes like a habit, I think we lose some of the bonding power that could have been for the one we were intended to mate for life.

Yes, you being young means you are dealing with a very strong desire from those feelings. I had a friend like yours when I was a junior/senior in Highschool. I had been friends with him since he was in jr. high. I couldn't even stand that he had other regular friends and spent more time with them than he did with me. How's that for selfish ;-)

Still, true love is not the act, it's the life around your friendship. You are concerned you might lose him...Are you concerned you will lose the friendship you have built or just the chance for sex? Another illustration I have given my students, is that, when we finally have the partner we will share our life with, sex is unlimited, and we have the rest of our lives to enjoy it.

Here's the timeline:

----wait for it---PARTNER--------------------SEX-----------------------

I don't know about you, but in those 50 years are a lot of sex. It's most difficult now. But, if you are concerned about this, you are concerned about your friendship, he has come onto you and asked about lots of sexual issues, don't you think it's fair that you confront him on it? If you can candle waiting to find someone, shouldn't he commit to that as well?

I don't suggest you wait for each other to grow to be together--though that may be an option--I suggest what many students do, and vow to each other abstinence for a time. Based on your friendship, maybe just cool things off and let the passion settle. Then, consider the situation and take the next step--up or down. I just know that you are pretty far down on the staircase now, and I don't know if you have the light on or off. I guess, you've had a night with YF2, controled, now YF1 has taken a few steps down from that with YF2, and only a few weeks ago, wasn't he teasing YF2 about even sharing a bed with you?? He's farther down than you now, but he is in arm's reach. I suggest trying to pull him up a bit to your level. Try going up more to the top of the staircase, with the light (of God) and prayer on your side, and then see what comes of it.

Pray, pray, pray. Every time you feel anger. Pray, and out loud, rebuke it. Every time you feel jealous, pray, rebuke it. Every time you are tempted, pray, rebuke it. This is how Jesus handled temptation in the dessert. He spoke out against it. If it worked for him, it can work for you, and your YF1 and 2.

Good luck,
Oliver
