It's pretty plain and simple, unless one wants to justify sexual sin. Married sex is the only sex God is okay with. Can sex be for mere intimacy and pleasure? Answer this: is sex pleasurable? Why do you think that is? God made sex for two things: procreation and intimacy. I am not here to answer for the failings of teaching on sex in marriage by pastors I do not know and am not accountable for. I am here to say, as I did, quite plainly, that sex is for marriage. End of story.
And, sorry to disappoint you, but I will not jump on your bandwagon to make divorced and remarried Christians feel like second class citizens just so you can soothe your conscious on sexual sin you want to permit for others or yourself.
