I am pleased to report that my sebaceous cyst/undescended testicle is gone.

I put a gel cover on my saddle and that was enough to change whatever was going on to cause the thing. My saddle looks like a grandma saddle but I do not care - my crotch is happy. The jellybeans are gone. Yay!

I've been testing new saddles - so far no dice. But I'll keep trying.
