There are no further viable options except for the ones stated by G-Lex and quoted here by the Rareboy. That's how the cookie crumbles this time.
I also see that you have been actually given loads of good advice here and that your first thread, with your admittedly, rather confusing postings got altogether 25 posts. This is not bad by any standard and should not give you any reason to give up on JUB, for that matter.
It will also make a lot of sense to keep the things in prospective. You and your friend are still teens. A lot is changing in your lives and your sexuality may or may not be determined yet. You cannot speed it up for anyone, no matter, how hard you may be trying. He has to get to his own, at his own pace alone.
I have encountered a bit of a similar situation in my HS and college days. My best HS bud and I ended up at the same college. He was a first class hottie, restaurant head-turner, 1st class athlete and a smart and nice guy to boot. We used to be fooling around a bit in HS, stayed absolutely the best(est) of buds and all was good. My gaydar was telling me that he was as straight as they come. I had to scratch him from my infamous list, and I did.
Being friends, we were hanging out together practically all the time. Both of us were getting hit on by both gals and guys and I was after the few hotties with all the moves in my book. My sexual life was a major banquet and I absolutely loved it. On the other hand, my bud was turning down absolutely everybody. This girl was too short, the other one was too tall; one day he did not like the dark hair, the next day he had nothing for the blonds; no one, but no one was good enough. Indeed, he had every single right to be choosey and picky, but this was going too far.
So, I asked him about it, and he came up with the usual, 'I want my sexual life to be meaningful. I want to date and I want the romance and the candlelight dinners and all that



. We are talking an 18 year old horny and very healthy college kid. Cool. His life, his choice. So, why was he not dating and going on with his program? He did not know. No one was good enough.

After a while, I started suspecting that he was simply too afraid to have sex. (I know, this sounds weird, in the least.) One evening, he opened up and spilled it all out. What, if he fails to bring her to orgasm. What if he looses erection? What if she laughs him out of her bedroom? What if, Yahda, yahda...
Though I was only 3 days older than him, I had had loads of experience. (Having started messing around at the tender age of 12, I knew more about it than most other dudes of my age.) So, we talked it out. (What else are the friends for?) We even had sex that night, which turned out to be some sort of a closure on our HS past, and sadly on our friendship, too. But, he was encouraged. In a matter of a week, he was dating a very cute blond girl and he even phoned me, some two weeks later to tell me, that yeah, they had sex and it was all great and good.
As these things go, we started drifting apart. He was spending most of his time with his new GF (with more GFs to come) and I was marching to my own drums, too. Over the time, he stopped answering my calls and I called it quits, too.
Start considering the fact that he simply may be too afraid and to shy to try anything with anyone. A somewhat weird option (no pun intended) but probably not that uncommon at all.
