Hubby here. Bought this for a weekend excursion. Wife is into the temperature changes vaginally. We contemplated glass dildos for some time, but never made the move. We cooled her new glass dildo in some water. After "some other action" I got the dildo and touched the wife in a number of erogenous zones and she responded with great pleasure! When pressed against her cootchy lips, she gasped and moaned such that there was no mistake that she was into it. After teasing the "area", I inserted the cool glass dildo into her happy place and she went wild. The temperature differential was working its magic. This dildo seemed to be a great fit. It is a little smaller in length and girth than I am, but she was very much into it. It is super smooth, but has the swirl on it that seems to work quite nicely. I base that on the fact that the wife comments about the veins Mr. Happy has that she finds super pleasing. So....I think this glass dildo will stay close by the bed at all times. It is an awesome extra when she wants some slower smaller, super slick, gentle stroking and probing.
