Not at this time, perhaps a raincheck.

I generally don't make it a habit to sleep with people on a first date.

[He was usually too oblivious to know when he was on a date and had only really slept with exactly one person, that event being recent. He didn't feel like sharing that though. So he did the sensible thing and ordered another gin.]

However, I don't really understand how one can be so casual about something so intimate.
