So, I got my first packer/stp.  It's this (I hope the link works): http://www.early2bed.com/mm5/merchant.mvc?Store_Code=ETB&Screen=PROD&Product_Code=STPILF

I made a makeshift harness out of shoe strings, but now I'm kinda paranoid... I'm worried that the glue holding the nipple in place isn't going to hold and that my crappy harness is going break it somehow.  I mean, maybe I should buy boxer briefs to keep it in place instead of a shoe string harness? 

Also... is it normal for it to be riding down my pant leg when I'm sitting down?  Sorry for the odd questions...

I don't know if that model is durable or not, as I don't have one...But I remember looking at them, until I decided that I wasn't brave enough to make an STP my first packer purchase.

Hmm...I'd be afraid to hold my in place with shoe-strings, I use an empty jock-strap from Walmart, keeps in place. But it eventually stains from rubbing on jeans (If that bothers you) ...I wear tight pants...so it might not happen if you don't. I wish I knew. I would definitely put some boxers over the harness though until you get something a little more durable.

o.o; Like...how far riding down? Mine usually sort of shifts to one side when I sit, but it shouldn't be like...sliding down to your knee...that's not normal.

Yeah, I was wearing some boxers over them, but the harness was still making me kinda paranoid. 

Okay, I guess that's normal then.  It wasn't going down to my knee or anything. xD;;  It was just shifting to one side and I really wasn't liking that.

I actually just got back from Walmart.  I got fed up with the crappy harness + boxer combo and broke down and bought some boxer briefs. xP  I've always liked boxers more, but the boxer briefs hold it in place better..

So I guess that kinda resolved itself. xP

I'll tell you my experience with a similar STP device. The penis was realistic enough, it wasn't like anyone was going to be looking. And the funnel part was the same on mine (though, I'm sure it was a different model, from the Tool Shed though I will not buy from them anymore).  When I pulled it out of the package, I really liked it. It was very easy to get used to. However, the funnel was separate from the tube inside, and within a week it had broken off. What had actually started first was the pee hole had started peeling and the tube was revealed. It was wide and I wasn't sure how that would do for a stream...Then it just started tearing, and got worse, and worse... Then when the funnel came off, I was upset. I was stupid and bought a second one, same model, thinking oh, mine was just faulty. Nope. Two packers completely wasted and I would never recommend them to anyone. Again, like I said, I'm not sure if yours would do the same to you, but I just want you to hear my experience. The only purpose it serves now is a sh*tty packer just to feel a little more like a man than without any packer at all while I wait for my Reelmagik to come in.
