My significant other very kindly gave me one. I don't say this to float my boat, but I pretty much can't fit in it at all, except for about the head and not much more. What I mean is that circumference-wise there's not nearly enough room. Hence it's just too tight. However, I'm not at all saying they'd be this way for all guys, nor most. And I do think there can be varying sizes out there. And unless as a matter of personal preference you would like yours either impossibly or just extremely tight, I wouldn't see anything wrong in getting the largest you can find. Also, I've tried stretching mine out to see if that helps. I can still say I've never experienced any other natural, perfectly normal, holes being so tight. But again, I think my experience might just be unique to me, for whatever underlying causes you might want to impute. It seems other guys get plenty of pleasure out of them.
