Answer: Ephesians 5:3 tells us, “But among you there must not be even a hint of sexual immorality, or of any kind of impurity...because these are improper for God's holy people.” Anything that even “hints” of sexual immorality is inappropriate for a Christian. The Bible does not give us a list of what qualifies as a “hint” or tell us what physical activities are approved for a couple to engage in before marriage. However, just because the Bible does not specifically address the issue does not mean God approves of “pre-sexual” activity before marriage. By essence, foreplay is designed to get one ready for sex. Logically then, foreplay should be restricted to married couples. Anything that can be considered foreplay should be avoided until marriage.
