ONE FINAL COMMENT
"With a high enough surface tension"
Do you understand the effect of silicone (used as a condom lubricant) on surface tension?
At around 50 centistrokes you could 'kiss surface tension' good bye.
Other condom lubricants have a similar effect.
That would be 5K strokes. Eather you are stroking MUCH faster then me, or you are reusing your condoms.
Lets be generous, 30 minutes/5000 strokes = 3 strokes/sec.
Still I'm with you on your endorsement of Polyurethane condoms. They are will worth the extra money.
