Men, if you invite a lady to your apartment on a date?

Say you've been out four times and havn't kissed yet. She seems a bit reserved but probably interested in you as she always replies to your messages and even invited you on one of the dates. Say you invite her to your house for the fifth date. She asks 'where will I sleep' and you reply 'there's a sofa'. Are you expecting her to sleep with you? You're both in your 40s, single without children.
