In essence, Paul is saying that we need to learn to control ourselves.
We are not to take advantage of others – whether it's taking physical liberties or pressing for another type of intimacy.
Ephesians 5:3 says, "But sexual immorality and all impurity or covetousness must not even be named among you, as is proper among saints." The New International Version puts it this way, "But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people." Anything in a premarital relationship that hints of sexual immorality – like dry sex, foreplay, nudity, sleeping in the same bed, pornography, and the like – is unacceptable.

Depending on one's culture and one's typical physical contact with others, physical boundaries may vary. This is not a sign of intimacy or love so much as it is a greeting. It is also important to look at the degree to which the physical touch is carried out.
