Tight silicon sleeve
I read a post while browsing the forum where someone had used a silicon sleeve together with a condom while pumping in order to protect his penis from doughnut when pumping at a very high pressure. I then remembered that I have a silicon sleeve ("Crystal Skin") lying about, bought it of curiosity but haven't used it since it was too tight. But it is stretchy, so I thought I'd give it a try in the pump. Squeezed in my semi-erect penis into the sleeve then and inserted the package in the pump and did a pumping session. But the sleeve is too tight, especially for the glans. So now I am considering if I shall try and cut off the top of the sleeve and use it as a doughnut-protector below the glans....

Also, I started doing kegels during pumping. Haven't done that before.

* NOTES for week 20 *
Monday: Jelq, 80 strokes (40 reps) during 10 minutes. Then uli 3*45 seconds.
Tuesday: Pump, 10 minutes at 6 inHg and kegels. 20,2 cm (7.95 in) in cylinder. Directly afterwards BPEL = 19,8 cm (7.80 in), MSEG = 13,6 cm (5.35 in).
Wednesday: Pump, 15 minutes at 6 inHg with silicon sleeve and kegels.
Friday morning: Jelq, 80 strokes (40 reps) during 10 minutes. Then uli 3*45 seconds.
Friday evening: Pump, 15 minutes at 5-6 inHg and kegels. 20,2 cm (7.95 in) in cylinder. Directly afterwards BPEL = 19,8 cm (7.80 in), MSEG = 13,8 cm (5.43 in).


Remark: 4 mm has been added to all in-cylinder measurements since they have been done with an extra latex sleeve mounted on the cylinder. This adjustment gives values consistent with measurements made before this extra sleeve was mounted.
