Never see this discussed but I can't be alone. Please don’t hurt my urethra. Forceful rubbing or probing is excruciating and will end love making immediately! Nothing worse than being in the throes of passion when your lover, whom you trust with your must intimate parts, goes groping to pleasure you and ends up trying to insert a finger into your urethra. Imagine if I tried to insert my finger into the tip of your penis. OUCH! Much less likely to happen if I am turned on and lubricated. I ALWAYS try to make positive statements. "I love it when you, feels great when, really turns me on when you.” But guys need to know that spot is not for penetration. It may be difficult to express in "positive feedback" speak. Except to say "Please be gentle with my urethra. She is a delicate flower who appreciates a tender touch." Gentle kisses, licking, even rubbing are ok and even great. Please consider adding this to your "things to never do in bed" list. THANKS!
