Clamping question

[j123]

Is it better to do 3x10 minutes of clamping or 2x15 minutes of clamping?

My choice would be the latter.

My choice would be 3 x 10 mins. This way you get fresh blood into the penis more often. Also, during 10 minute + sessions I've found that erection level gets lower and lower as time goes by.
