Am I overthinking or is my ex right?

So I just got done talking to my ex (we're friends now) on the phone and he brought up a great point about my date on Saturday. The guy is coming an hour away at 9pm. We're going to be at an arcade/bar/restaurant.

My ex brought up that he may want to stay the night at my place since it is a long drive back late at night plus it will be raining that night. He kind of suggested if that were to happen that things could lead to something more happening.

I'm so not prepared mentally for sex on a first date. I'm not even prepared for him to be back at my house, but I can understand why that may be the courteous thing to do since he's coming an hour away. But I hope he doesn't expect there to be sex involved.

I don't know where his head is at because we haven't really talked about that kind of stuff.

But a part of me doesn't trust myself being alone with him in my place because I am very sexually frustrated and honestly if the date goes well don't know if I would give in. I didn't tell my ex this but I feel like I would.

Does that make me a slut if I were to do that?

Maybe I'm overthinking this. Maybe we will just go our separate ways after the date but if we don't, I don't know what I'm going to do.
