Many moons ago, in my heady pre-DH days, I had quaint notions about getting to know people before I slept with them. Therefore, after a few dates I might say something like "You're welcome to stay the night, but just to be clear, I won't be taking my pants off". (NB this was when living in London, when any post-tube journey home was likely to be either expensive or extremely lengthy, or both.)
One young man agreed, then spent the night arguing with me about it - apparently I was being totally unreasonable to stay the night without being prepared to sleep with him. Another one didn't argue verbally but spent the whole night trying to remove/get into my pants (and then demanded breakfast) 
When I complained about this to a friend, she said she thought it was weird and a bit aggressive to have said explicitly that I wouldn't take my pants off. I just thought it was best to be upfront from the start.
So not exactly terribly urgent
but my friend's response has been niggling at me for a few years now ... WIBU or was she? Was it weird or sensible to be upfront about what exactly was on um offer?
