The conversation came up casually away back at the start of my relationship and I told my partner honestly, he told me his but I now suspect he claimed the number to be smaller than what it really is. More I've thought about it, I know a few of my friends have lied to their DP's about it too.
I think it's a conversation that comes up in most relationships at some point (might be wrong) but I wonder how many people are totally honest about it?
