When it comes to kissing would you settle for that 1 person you could trust or the pleasure of promiscuity?

I definitely wouldn't go behind my husbands back doing that. That being said if you both agree on the boundaries of your physical experience with other people I think it's ok. The reason I can say this with honesty and full knowledge is my husband and I are swingers so we both agree on our limitations, but we never go behind each others backs.
