If you heat up in hot water, as per instructions, then apply lubricant to all the relevant parts, you are absolutely good to go. And believe me, 'go' you will, because this little beauty feels like the real thing... No messing. Can't believe I've got to 42 and only just discovered it!
I knew I love it once I saw the head come out of my mouth. I couldn't breathe and I loved it. I'm now in a wheelchair but it was definitely worth it :-)))))
