I've been clamping with bends recently and my curve is almost straight. It amazes me. I had a curve that leaned terribly to the left and used bends to the right to straighten it out. I'll be posting some new pics in the picture proof section soon to show the difference.
I really recommend getting a cable clamp and doing bends. This accompanied by DLD Girth Busters is the ultimate in a girth workout with straightening in mind.
Yeah, those cable clamps or other types of clamps work really great with exercises like erect bends. You can really concentrate on the exercise without having to worry about erection level and maintaining your boner
DLD bends while clamped have been kicking my dick's ass lately. My flaccid girth is really looking bloated and my erect girth seems to be improving too.
