Re: date him just for the experience?
I think you might be putting the cart before the horse here, Jane. I didn't hear anyone mention 'Going out' (that's with a Capital 'G', if you know what I mean). What I'm hearing is that he wants to see a movie with you, maybe grab a bite to eat.
I say you should lower your expectations, look at this as just 2 people who have something in common spending an evening together. It's not necessarily a 'Date'. Go for it, just enjoy the evening and maybe eachother and see how you feel at the end. Don't read anything into it.
