In the past, a man would need to court a virgin woman for months or even years and then ask her father for permission to marry his daughter.
Once he got that blessing, they could get married and then begin having sex and living together. According a study in the USA, 55% of couples admitted to having had sex on their first date and a European study found that 70% of women have had a one night stand before.
also, what's the difference between what people DO on a date and what people do when they hang out?
do you act like boyfriends/grilfriends when you date?
Many in a courtship relationship will not spend any time together unless family members, preferably parents, are present at all times.
In addition, courting couples state up front that their intentions are to see if the other person is a suitable potential marriage partner.
As stated before, during this time there should be little or no physical contact, as this is something that should wait until marriage (1 Corinthians -20).
