I went through a similar transition myself right around that time as well. I suspect the Holy Spirit was moving on the earth at that time to help us to have greater understanding.
My personal views today have caused me to ask the question is sexuality really an expression of love at all. But that is probably another conversation.
As society stands today I cannot in good conscience say that cohabitation should be allowed in one "circumstance" and not in another.
Another powerful dynamic that humanity is on the verge of exploring in a new way, imo.
