However when 2 equals, such as closely aged sisters engage in physical contact of a sensual nature I think that it is just a societal taboo that has no basis in real morality.
I think the taboo in part came from the possibility of reproduction, but that's not even an issue here.
It's not my thing (to the point where I personally find it offputting), but who am I to judge another person for an activity which is consensual and hurts no one? It's not my body, not my life, not my choice. Period.
Also lol @ the church comment...I would be weirded out and immediately leave if a visitor asked me to go to church after "our debaucherous time". uhhhhh...if you feel you did something wrong enough to repent for perhaps you shouldn't be doing it? or perhaps you can go to church alone.
Now if you're paying for the time, I'll go to church and sing with you. No problem.
