Made my own divice

Yesterday i was at the hardware store and came up with the idea of making my own chasity divice.
I brought a piece of hose that I thought i could squeze my dick into. I also brought a house clamp to fit around the hose.
I put it on and I had to use alot of baby oil on the inside of the tube and on my dick to get it on. Then i put the clamp on the base of it and tightened it up. I found a hose clamp with a key thing on it so i dont have to use a screw driver to tighten it.
I wore it yesterday for half a day and took it off last night as my wife doesn't know about it. I put it on this morning about 7am and took it off tonight at about 7:30.
I keept tightening it slowly though out the day and only losened it when i needed to pee and then tightened it up straight away. I looked at alot of porn today to see how it would work and there was no way I could get an erection.
Its been off for about an hr and I have no feeling and still cant get an erection from playing with it as I can't feel it. Not sure if the feeling will come back into it later (I'll test it out when my wife gets home )
Anyone else done anything like this?
BTW cost me about $4

Think you need to purchase the real thing...

Might not need to. Might be to late.
12 hrs after taking it off I still have no feeling in it.
Wife made a move on me when she got home last night and I managed to get about a 3/4 of an erection but there was no way i could cum as I couldn't feel anything when we were fucking

You gotta be careful with that kind of stuff. The same as anything. I've made plenty of my own devices, but you never stick a pencil up your cock, you never stick a raw egg up your ass (even a hard boiled one should be taken out of its shell first), and you never squeeze your cock so hard you can't pee unless you're trying to rupture veins. Some more you nevers for the sufficiently wasted: You never go to bed with your balls tied tight. You never stick your fist up an ass or vagina without filing and smoothing down your nails. You never put all your weight on a long solid object up your ass.

By the way the cheapest chastity I ever made, I made for free. Using a thin cord I already had, I bent my cock between my balls and then used the cord to tie it down. Worked fine, cost nothing, and I removed the damn thing every 30 minutes to ensure no permanent damage was done.

I still have no feeling in my cock. I can get a full erection now but fucked my wife the other night and pounded like never before but i can't cum as i cant feel anything but fuck it was a good workout. Sweated like mad

Still have no feeling. can get an erection but I just can't cum as I can't feel anything.
I am now her for only my wifes pleasure and not mine as she can bounce on my cock as much as she wants when ever she wants and its all about her.
