Thanks for the responses, guys. It's good to know I'm not the only one who feels this way.
lol I had to laugh at the dick hanging out on the clothesline, Sebryn

I've looked at the rodeo and even tried using actual underwear as a harness, but it still has an effect because I think that what is really bothering me is that I can't be naked during sex - it's always either a harness or underwear or both.
@ Brett - yeah it sounds like a pain going through the process of adhering it - but I'm prepared to do it just because I want to try anything at this point. You can wear it like a packer, too - it's just probably bulky, but I wear baggy pants at work anyway so hopefully it wouldn't be noticeable. I'll just have to wait and see.
I guess I like the idea of: a) it adheres to my body and means I can be naked an look down and see what appears to be a real cock, b) it looks and feels close as you can get to the real thing and c) it can be "bent" to an erect state, which means our sex doesn't have to be timed or planned or awkwardly interrupted so that I can "gear up".
Anyway, yeah - I suppose I'm just looking at my options. I don't know when I'll get the money to have bottom surgery at this stage because we're prioritising a house and kids (she's already nearly 30). Maybe the RM will at least be something I can live with until we do have the money.
**Oh I forgot to add about the Vix skin cocks - no, I've not tried them - but the don't look very realistic which is what's bugging me about the ones I currently have. The worst, as far as smell, is the one I have from Doc Johnson. I do not recommend them as the smell is honestly just overpowering and hasn't faded in 2 years. I've washed it, let it air, nothing helps it.
