Hi Swede:
Here’s a weird little trick I do to keep from getting hard when I’ve put the wrap on (it’s bizarre but it works for me).
I take the weights I use (gym plates attached together with a bent wire coat hanger) and lay them on the edge of the chair I’m sitting on. Then, before I put the wrapping on, I rest my balls on the plates. The temperature of the cold metal seems to take away any interest I might have in an erection! And yet it doesn’t actually touch my dick, so I’m not causing the ligaments to grow cold. Then I wrap, and then attach the hanger, and then attach the weights. Usually it stays soft.
Hope that helps.
