During surgery? DO they do it while its hard or soft, im being very serious here, a few of my friends were talking about this and we all had different ideas. Please be serious and explain in detail Thank you!

Doctors and surgeons insert the catheter into the penis while it is flaccid because it is more flexible and also for a reduced chance of blood clots.

I-ve worked in nursing homes and rehab centers and you insert it while it-s soft. If it was hard you would not be able to insert it correctly and would cause a lot of discomfort.
