Couples who want to meet a single woman mention it on their profile, so you'll know before you reply.
Hear from both of them
Before you agree to anything, check that both partners are chatting with you and both are keen. A group chat with the two of them makes that easy.
Know their rules, and add yours
Ask what's allowed between you and each of them, and say what you want too. Your limits count as much as theirs.
Plan your exit
Decide in advance how you'll get home, and feel free to leave at any point. Any couple worth meeting will respect that.
