So after a week of being off completely, I came back to 1x20 minutes at 2.5 lbs (had left off at 1x20 minutes at 1.5 lbs) and the small, flat blood blister is back (same spot). Still painless, but certainly undesirable for both aesthetic and safety purposes.
Checking through my logs, it seems that this never became an issue when sets were limited to 15 minutes, OR when the resistance is <2.5 lbs.
I check on my penis pretty frequently throughout the sets, and this blood blister always only seems to return after more than 15 minutes. If I can do 2x15 minutes at 5 lbs (for a total of 30 minutes volume) safely, and get more expansion out of that, it seems that 1x20 is a waste. That being said, I did 14 sessions over about 3 weeks at 1x20 with 0-1.5 lbs and no injury.
Since it’s in the same spot and has healed to the point of invisibility multiple times, I am a bit concerned if it’s possible I ruptured a blood vessel permanently and won’t ever be able to safely go over a certain time or resistance again.
That 5/8” expansion after the 2x15 minute at 5 lbs session was so glorious! I hope I can get back to that at some point.
For now, I am going to let it heal back to invisible state, and then switch to a hanging cycle so it has some more time to recover while I work a different dimension.
When I get back to clamping, I’ll just do it weightless and in 15 minute sets until my current typical expanded size (4.875”) cements to become my regular MEG, and only add resistance if absolutely necessary to expand beyond basic MEG.
