That looks like a 16g size. The 30g or 32g is a lot smaller. Do have those on standby.
For now, if you want to use that, go for it. The remaining lance puncture may be larger than I want.
When lancing using a medical needle, the smaller puncture is always better. The fluid will seal the puncture site back up in 10 minutes. When you lance the blister, lance close to the base of the blister as much as possible without puncturing your glans, and the lanced location around the edge should be far away from the urethra where the most bacteria tend to accumulate. With that large needle, only lance a very tiny bit to allow fluid to start the flow out. Do not lance it so much that the fluid gushes out. That hole will become too wide.
When the fluid starts to trickle out, do not squeeze the blister. Rather, use a dressing, toilet paper ply, or cotton pad to put over the blister. Gently, so gently, roll you finger from the opposite side of the punctured side towards the lanced site. You don't have to worry about removing all the fluid. Just enough to relief the blister from causing any more expanding.
