Lol @ Dildo cam. I soooo badly wanted to say that when i was describing but didnt want to offend anyone!! That is totally what it looks and feels like!! I have never been asked to insert mine, they just did it. Luckily i have had the same two chicks when I have had a u/s and I am pretty comfy just sitting there with my skirt up. lol.
I'm only recently (this year) comfy with that with DH!!! :P

as long as you relax they're fine.
