Can't say I didn't warn ya. This is definitely the nastiest thing that has happened to me during sex. I'm wondering if anyone else has had this problem, because I've never heard of it before. I've been trying to convince my hubby to do anal with me...well that was BEFORE I remembered this one time when my ex and I were doing it and all of a sudden he commented that he could feel "the tip of the iceberg." Amazingly, we laughed it off, but I think if it happened now I would die. So, has this ever happened to anyone?
