sneakersjay,
I can only speak about my experiences, of course. Yours may vary, depending upon the company you keep. I tend to keep company with a lot of gay/bisexual men who are into 'furries' (an unaccepted fetish by society as it is). Nonetheless, gay or bi men who feel unaccepted by society themselves (though not for gender related issues), are more likely to accept us. Personally, only a handful of guys who I've told (and who were attracted to me) were put off by it (they were complete 'bottoms' and thus my lack of male equipment was too much for them to get over) and were no longer interested. Others were put off, but gradually accepted it and even forgot about it. And others still were actually -more- attracted to me (usually the 'tops'). All were equally as 'grossed out' by going down on 'chick parts' though. But that's understandable if they identify as mostly gay.
So I'd say you'd be pretty desirable. LOTS of guys are attracted to transguys because damn...we're HOT. =D
Hormones were definitely worth it for me. You'll get the body/facial hair, the deeper voice, the slightly different facial structure (fat redistributation), more muscle tone, and overall your body will look different and more masculine. It also changes you mentally. of course your sex drive increases. Your orgasms become more intense (mine did anyway), and your penis (clit) will get larger. Mine's about the size of my thumb. You will get random boners too. It's great! Likewise, top surgery and a hysto were definitely worth it for me. I was very large up top and I had them removed, and started T, within 2 weeks of each other.
Lower surgery...well...that's another story. I recently had a less invasive metoidplasty (just a release, no ligaments were cut, no urinary hook-up) and testicle implants, and to be honest, I regret the decision (and am meeting with the Dr. to potentially have it 'reversed') and would advise anyone thinking about it to consider WHY they're getting it and whether it's worth it (it certainly hasn't been to me...I feel like I made a 7k mistake).
There are lots of different trains of thought. Some guys are only happy if they have all of the surgeries (lower included), and they're happy with the outcomes. Some guys don't want surgery at all. Some don't want to bother with lower surgery because the available surgeries are expensive and leave a lot to be desired. For me, when I first started, I had to do everything---I was sure that I would not feel complete without getting a phalloplasty or lower surgery. But after I had my hysto...I don't know, it wasn't important to me anymore. I felt like a man. Even if I had chick genitals, no one knew but me, my family, and my lover. I was happy. I had found peace with who I was and what my body was. Everything functioned like it should---I got pleasure out of it (a lot...*Cough*), and lower surgery just wasn't a priority or necessary for me. I liked the way I was, chick parts below the waist or not. It took 26 years, but I came to peace with my chick genitals. Adding to that, the surgeries for transguys are just NOT sufficient (even the Dr. who did mine admitted this). I wouldn't advise -anyone- get a Phallo, simply because of the risks, costs, and lack of sensation. Metoids...well, SOME guys can pull them off, but usually it requires a more invasive metoid procedure that involves cutting suspensory ligaments, urinary hookup, and formation of a single scrotal sac....and even then you're left with something that's not going to let you 'pass' in the locker room half the time (ie: doesn't look enough like a bio male's equipment...at least to me).
I've never used a packy or anything like that. I never felt I needed one...as I mentioned, I made peace with the fact that I would never be like a 100% biological male...not until the lower surgeries improve drastically and become less costly. But I view myself as male, my partner does, my family does, and society does...that's all that matters to me. I'm a guy with a vagina...and that's just fine with me. I don't hate vagina (I'm bi)...I don't think chick genitals are gross or ugly or anything like that...even on myself. Now don't get me wrong, I would love to have a penis and balls and all of that, but not at the risk of complications, lack of sensation, lack of -looking- natural, cost, ect. I would much rather be happy...and I was before I got my metoid (now I feel like I'm a herm, locked in some genital limbo...extremely unhappy and just wishing the Doc will reverse it so that I can be happy with myself and my body again).
But as I said...everyone's different. Some guys -need- the lower surgery to feel complete and they don't care about the outcomes provided it's better than what they had before. I didn't (which should've been a red flag to my psychologist, but that's a moot point) I did it because of the potential to penetrate my partner with my own body and to look more masculine below the waist (and now that I have it I don't believe it accomplishes that satisfactorily, at least for me and my body type)...essentially to make me happIER, not happy.
If you do decide to go for lower surgery just make sure you do it because you feel it's necessary. I know at the time we don't think about the risks or complications...we want to think everything will go great and we'll be fine and we'll be one of those lucky few where everything is just PERFECT. Rarely is that the case. The surgeries don't accomplish the same results for everyone...on one guy it may look great, he may even look close to a bio male, but on another guy (even with the exact same surgery from the exact same surgeon), it may not accomplish that...differences in body type play a HUGE role in how it'll look on you compared to the photos you see and compare to. Make sure you get letters of referral (2) from therapists who've had trans patients before. It's their job to pick up on anything that may give them the impression that you're doing the surgery for the wrong reason (and thus it may not be the right choice)...obviously, if you want it, you're not going to think it's not for you---everyone is optimistic about these things. So just make sure you do it right if you're going to do it. Personally...I'd rather just accept my chick genitals and be grateful for the fact that I'm a very unique individual who is a man, but gets to have the additional pleasure of having chick genitals.
And I think it's a very guy way of thinking too. Ask any straight guy what he'd do if he woke up with boobs tomorrow, and 9 times out of 10, they'll tell you they'd play with them, not have them lopped off. =)
