Hello ladies, gentlemen and those somewhere in between!

I'm FTM, I've been on T for over three years and I've starting wearing my packer daily for about 3/4 of a year now. So far, it's been (mostly) great. I've had some embarrassing (and slightly amusing) mishaps where my penis (I think of it as my genitals, despite it being a prosthetic) falls into the "leg" of my boxer-briefs (I learned I can't wear briefs anymore, 'cause it will fall out of them, for some reason). and moments when it looks like I have a raging erection because my dick is awkwardly shoved in my pants. So far, I'm really enjoying NOT having to stuff my pants with socks. I pass like a boss and I'm pretty comfortable changing (down to my underwear and undershirt, which is over my binder) in front of other people and I'd consider myself confident in most social situations (the exception being the common misconception of despite being FTM, I have NO idea how to court women, but that's another story). My dick doesn't look exactly realistic sometimes, especially when I'm just in my underwear. That, and I'm terrified that it's going to FALL OUT of my underwear.

Other bits of pertinent information: I'm very physically active, and among other things, I am a dancer, so not only do I have to wear pants (tights) similar to yoga-pants material, but I have to be able to move and do crazy stretches. I also tend to wear tight/form-fitting pants outside of the dance studio (mostly skinny jeans). I'm fairly skinny (I wear sizes 30-32) and I'm 5'8". I'm an actor, and I will be studying theater in college, so I will NEED to change in front of other people without them being suspicious.

Anyway, I'm going away to college in about a month, so I imagine my living quarters will be a little closer (I'm in a quad for three other guys) and I'm wondering if anyone has any tips for making the bulge (in underwear or tights) look more realistic. Where does one place the packer? How does one keep it in place so they're sure it can't move? I've tried wearing two pairs of underwear before, but that got old, uncomfortable and suspicious quickly. Any tips?

They have youtube vids of easy to make harnesses. Check into them. I do well with some simple elastin homemade stuff.

I wear boxer briefs without anything getting out of place.

Just a thought--wouldn't a lot of male dancers wear a jock? Seems like maybe that would solve it?

EDIT: Out of having nothing better to do ( )  I just looked it up, and discovered that male dancers use what is called a "dance belt."

Well, if you learn something new every day, I guess that's mine!!

 steampunk_knight,  I don't wear a packer regularly to afraid it will slip and I will look like I have some kind of a hard on or worst fall down my leg.  I am in college but live alone so no problem so problem with other seeing me when I am home.  Living with 3 guys in a quad should be interesting, do you bind all the time, are you on T or still get shark week every month?

google "worlds simplest packy harness". That's what i used to use to hold my penis in place before surgery. also, line it up with your biological dick and it should sit right. Like right below your pubic bone.

I use a jock strap and then cover the jock strap with boxer briefs.
