1) I'd question your certainty that your final destiny is secure if you deliberately ignore what you know God wants. The passage in Hebrews 6 suggests the contrary:

4It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, 5who have tasted the goodness of the word of God and the powers of the coming age, 6if they fall away, to be brought back to repentance, because[a]to their loss they are crucifying the Son of God all over again and subjecting him to public disgrace.

7Land that drinks in the rain often falling on it and that produces a crop useful to those for whom it is farmed receives the blessing of God. 8But land that produces thorns and thistles is worthless and is in danger of being cursed. In the end it will be burned.

2) The monastic tradition points to the possibility of chosen celibacy. I recommend 'An Experience of Celibacy' by Keith Clark (available on Amazon) to show you how one guy has dealt with the issues. The most important single thing is to find real friendships where you are wholly honest and accepted; this is, ultimately, more important than sex! What isn't the case is that you can only find such intimacy in permanent one-on-one relationships; rather we celibates need to have a lot of such friendships. From a Christian perspective, regularly praying with those people is very bonding; I'm bemused but deeply encouraged that one friend who I only prayed with for a few months regards the quality of fellowship we achieved as greater than that which he presently has with his wife. And don't undervalue the possibilities of on-line friendships; this board is an obvious starting point, and has been very valuable for me.

An important element in that is learning appropriate touch; there is real value in totally non-sexual hugs and touching, something which the hyper-sexualised West struggles to allow as all touching is liable to perceived as sexual even when it is not. I remember once rubbing the chest of a cute 16 yo Turkish waiter at a hotel I was staying at because he was cold - it was not intended sexually, and it was not taken as such, because it wasn't an issue in his culture.... That's an extreme case, but it's worth working at getting as many hugs as you can!

3) Don't assume that you are gay to the point that a hetro relationship won't happen. Both the ex-gay movement within the church AND the experience of secular gay activists e.g.

http://en.wikipedia.org/wiki/Tom_Robinson

is that people do sometimes surprise themselves. And our own Cat is a demonstration that a successful marriage can occur even when there's little sexual attraction there.

4) I'd warn you strongly against developing gay relationships; once you're inside one, it will be far harder to get out than if you keep clear, and I suspect it's a route towards 'crucifying the Son of God all over again' for you because you are opposed to them. (It's not certain, but it seems likely that God is far more concerned with the issues you perceive to be wrong than some objective standard; the slave owners of the past are not going to be heavily punished for it, but if we had a slave now, then we would be.) This means you'd probably be wise not to come out publicly as gay - though you do need to find friendships where you are out. You certainly need to avoid the gay sub-culture - though it is comfortable, it is also a route to what you perceive as temptation - something which we are told to flee...

5) Given that you are going to j/o

a) Beware thinking of someone in particular when you do so.

i) This seems to constitute 'tthinking lustfully in your heart' far more than some anonymous person.

ii) This creates a willingness to have sex with them if they offer, which is asking for trouble if the opportunity does present itself. It does happen...

b) Focus on the upper end of your AoA as much as possible, and seek to get it higher.

6) Find good stuff to get involved with. Try and 'get a life' in terms of being active and involved; as far as possible don't mope at home and let the pressures build up, but be active, especially in church things. It's from church involvements that I gained the close friends who are still a part of my life 25 years on... In that field try and find out what gifts God has given you and start to work to train up, develop and USE those. One of the issues in our society is that we disdain the ability of our young people to do anything worthwhile when they are still in education, but that just ain't so...

I hope there's stuff of value in there. Life is possible without A ONE ON ONE RELATIONSHIP - though I have to admit it is hard work. But from the perspective of eternity - the real perspective - I suspect you will look back far more positively on your life if you lived by what you believed than if you succumbed to what you regarded as temptation.
