The partner with the stricter boundaries should set the norm for the couple.
All that being said, there are certain physical boundaries that are clearly biblical.
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.It is also inappropriate to be naked in one another's presence.Sex is a gift from God that is meant for a married couple to enjoy (Proverbs ; Song of Solomon; 1 Corinthians 7:1-4; Hebrews 13:4).Those who ask this question are usually looking for guidelines regarding physical boundaries in dating.However, intimacy is a much broader issue than physicality.
