Baseball bat dick is a common phenomenon. Generalized, girth gains happen where expansion and therefore stress to tissues happens. Many get that shape from just jelqing. I wouldn’t adjust your clamping habits by it. By moving the clamp upwards you basically just make your exercizes less effective as you are only attacking the upper portion.
All in all, If you really WANT a baseball bat dick, just start jelqing, that is a sure fire way to do it.
"Be aware that there are several schools of thought here as well. Some seem to go with the hard and heavy approach. The sessions are brutal. You can hear them talking to their dick: You better grow mofo or I will punish you even harder tomorrow! Others seem to favor a more tender approach. Always listening to what their member is saying while massaging it gently and singing to it with a soft voice. If it is moody and not happy with new behavior, they always listen and are very understanding."
