I'm going to ask my date now, see what his intentions/expectations were on our 3rd date, I can tell you on date 4, at mine, there were no expectations of him or me as far as I was concerned... Lots of talk, a bit of kissing, mostly getting to know each over still. At no point did I feel any expectation upon me, no pressure at all. I rather think he'd have been surprised if I had jumped him.
Each situation is different, if we have a history of abuse and regrettable choices and don't yet feel comfortable or confident enough to trust our instincts and judgement, then I'd suggest that we'd not agree to meet in such a private setting. I know when I was less confident about being able to handle relationships, I'd have been extremely worried about everything, as I was scared of everyone and everything. I know myself better now, am able to filter out those who aren't kosher and trust my instincts better.
As I say, remaining able to get OUT of a situation is as important as judging a situation in advance.
We have to be responsible for our own safety, but we can not tar everyone with the same brush forever. MOST men ARE NOT rapists/dangerous.
Mumsnet is great, but remember people post here with their troubles, not when things are perfect. It's easy to lose perspective.
