Some context: I started dating my boyfriend a few weeks ago. All has gone well so far but we're both new to this so we're taking it slow.
The other day, we were with some of our friends playing a game at a friend's house and it ended late (around 1 in the morning). My boyfriend walked me home since it was dark and I lived close by. He usually takes the bus home since he lives a bit outside town, but it was late and the buses had stopped running. He instead had to take an expensive taxi.
I wanted to ask him if he wanted to stay over so he wouldn't have to pay all that money. We even have a couch he could sleep on if sharing a bed with me was a bit much.
However, I couldn't figure out a way to frame the question without it sounding like I wanted to "sleep with him", so I stayed silent about it and he took the taxi home.
I feel like this will probably come up again later on in our relationship as well. As the title says, any suggestions on how to invite a significant other to spend the night without implying sex?
