DIY self-chastity for Men?

First message here:wink: Hi there. I’ve just started doing self bondage sessions for the first time and really enjoyed them (I’ll be sharing a story soon)… However, I got carried away with excitement, had an orgasm, and lost that little urge..:evil: That’s why I’m keen on finding some short-term chastity gear to wear during my self-bondage routines 8) Do you have any suggestions or DIY contraptions that are simple to construct and use? Ideally ones that make it impossible for me to touch myself (get pleasure) while bound?! Any thoughts would be great. I’m nearly broke and can’t afford a store-bought one:cry: Could someone help a chap out? Jack:gag:
