I was thinking it would be a great idea too, but I am hesitant to share such things. Obviously us girls talk about things with our close sisters but I don't know if he would even be ok with me mentioning it. Plus once I tell her obviously she will have loads of follow up questions like how big, how painful etc and as shes only been with one man I don't think she could possibly know if it will be an issue either.

I also don't want to sour her perception of him by throwing out a red flag in the case it wouldn't be an issue. I guess I am just conflicted. He really is a great guy which is why I am being so careful about giving bad or incorrect advice.
