Sex chat between a couple
No one should be encouraged or coerced to do something he or she is uncomfortable with or thinks is wrong.If a husband and wife both agree that they want to try something (e.g., oral sex, different positions, sex toys, etc.), then the Bible does not give any reason why they cannot.There are a few things, though, that are never allowable sexually for a married couple. The practice of “swapping,” or "swinging/swingers," or “bringing in an extra” (threesomes, foursomes, etc.) is blatant adultery (Galatians ; Ephesians 5:3; Colossians 3:5; 1 Thessalonians 4:3). This verse perhaps lays down the principle for sexual relations in marriage.Whatever is done, it should be mutually agreed upon.Adultery is sin even if your spouse allows, approves, or even participates in it.
Husbands and wives are instructed, “Do not deprive each other except by mutual consent and for a time (1 Corinthians 7:5a).
This is a serious question, and I will answer it as best I understand the Scriptures.
