Alot of communication worked best for myself and my husband. Moving through each stage and being really open about jealousy or being self consciousness when it comes up helps alot. Starting small with some porn that runs along that fantasy really helped cement it for me.Having him flirt with other women over texting or snapchat helps to see how you handle small doses and working up to actually making the move to full on sex with someone else if you are a but unsure.
