On the first date? Give it more time than that. Oral sex, any boob touching or fondling, and intercourse, is a 3 day minimum. After the first 3 dates, then it is acceptable to go for it, but on the first date, nah. I'm a guy, and if I were really interested in a women by going on actual dates with her, I wouldn't eat her out after the first date.

If you're just after a one night stand, that's all it will be. Meaningless sex that has no attachment or commitments, so yes, maybe expect oral sex, but expect intercourse sex, but what fun is intercourse without the foreplay. Nap time, that's what.
