1 What makes my Willie Warmers different than others you may have seen online?

Mine are a unique design that feature an open ended which allows it to fit nicely when flacid and then lets you stick out the end when you obtain an erection.

2 Do I need to measure myself so that a Willie Warmer will fit properly?

No, most people will fit into the average size Willie Warmer but if you are thicker than normal you might consider ordering the extra large size.

3 Does it matter that I am extremely long?

No, remember that this Willie Warmer is designed to fit you while you are flacid.  The sheath is made about 4" long which will accommodate most flacid penises.  When you obtain an erection your penis will stick out the end of the sheath.  Making the Willie Warmer too long will result in it being bulky inside your pants.
