I would advise avoiding “occasions of sin”. If when you date you find yourselves alone in a private place with no chance of being seen or heard, you’re in danger of nature getting the best of you.
On the other hand if you go to places where you’d feel embarrassed getting “hot and heavy” with your date, you’re probably safe. Examples, a restaurant, a play, a concert, going out with a group of friends, going for a walk in the neighborhood, walking in a park in daylight, skiing, swimming at the municipal pool, going to a hockey or other sports game, playing tennis, etc.
There are plenty of things to do where you’ll be safe and get to know each other better. Surely a venue to talk is important too; one needs to exchange ideas, hopes and dreams! Dinner in a quiet restaurant is great for this, or sitting on the porch at home (when the house is occupied…). Also, get to know the potential in-laws, make them feel confident that you will respect their daughter or son. After all when you marry, the in-laws are part of the baggage, so you may as well start off on the right foot with them!
Avoid secluded parks at night, the house when there’s no danger of anybody being home for hours on end, parked cars in secluded areas, etc.
Somehow, most of our parents, pre-sexual revolution (at least mine were, as I’m a child of the 50s) managed, for the most part, courtship without sex, and were generally heavily chaperoned. They understood the meaning of “occasions of sin”.
