In addition to everyone else's points about how your views of homosexual relationships seems to be largely erroneous (they're really not so different from us heteros), bear in mind that if you were a gay male your potential pool of partners would be astronomically cut.
Think about it. The earth's population of straight men exceeds the population of gay men by many many times; so if you're looking for your soul mate or anything, you'll have a much much MUCH better chance of finding him, statistically speaking, in a straight man.
Unless... you're thinking gay is your "destiny" or something silly like that.
Also, might I remark, I doubt you'd be entirely happy with the result of SRS if you started it now. The earlier a transexual gets the work done, the smoother the process, especially if it's done before puberty.
I suspect this is a relatively recent thing, like you didn't have these feelings until you started developing sexually or sometime after?

That's understandable, some men wish they were a lesbian.
Yes but... usually only in fantasy. Typically it has nothing to do with transexualism and those men wouldn't be happy if they were actually women.
Not that mtf straight men don't exist, it's just more often not the case in regards to lesbian fantasies.
